Well we heard of her being seen getting into a cop car with Wilden prior to going missing and then when Emily watched her vidoes she mumbled something about being a coward but we see a red light flashing as the video ends. The Red Flashing light belonged to Wilden`s police car. Because Jessica was begging for someone to be sent I believe she had called 911 which is why they called back 15 seconds after she hung up abrubtly because they are trained to do so, the big question was who was sent? I assume Wilden was on duty and was sent that night. I think he and the Evil Red Coat are responsible for Bethany;s death but they thought she was Ali. Bethany was lured as a decoy to the home by Cece and Ali who plotted to lure out Ali`s harraser who promised Ali they would kill her that night. This exlains why the duo wore Red Coats in season 4 while trying to lure out Red Coat. Cece saw Wilden and Red Coat that night but knew the girl they killed was the decoy. This is why Cece was afraid of Wilden. She never saw Red Coat`s face and Wilden was a cop so what could she really say besides she helped lure the girl there that night and as a result got her killed. This is why Ali doesn`t speak of Bethany, if she and Cece hadn`t lure her as a decoy the girl would be alive. Cece glady excepted money from Jessica to keep quiet about something she saw that night, since in the letter it states both Cece and Jessica saw the fight with Spencer and Ali and Melissa stated she overheard the fight herself I am led to believe something happened next that has yet to be shown to us. Jessica paid Cece to remain quiet but for what exactly? If Wilden and Red Coat are indeed responsible for the death of Bethany is it quite possible Cece witnessed it as she did state she knew who killed the girl and it was the same person who was trying to hurt Ali now and what if I told you Wilden was a bad man? With that said she would of been waiting for the decoy to show up and meet someone Ali thought could be her harraser threatening to kill her, Cece stated she thought Wilden went to see Ali that night so he is most likley indeed beach hottie and Ali agreed to meet him only he didn`t show up alone. If Jessica saw the fight as well then she would still be outside and could of very well seen what happened.This is Red Coat`s story and not Charles, Charles hit Ali with the rock and has his own story and not involved in Bethany`s death but he did follow her that night when she escaped. So if Jessica saw Wilden and Red Coat that night and saw Charles hit Ali with the rock my guess is when Bethany was hit with the shovel, Everyone but Cece thought it was Ali but Jessica knows Wilden from when Marion died. We know those to are shady when it came to the womans death. Wilden filed the fake police report confiming the death a suicide and Jessica was on the board. So it is possible Wilden had something on Jessica and forced her to keep quiet using blackmail. I think the reason she called 911 that night was because like Ali she too recived a message from -A stated Ali would be killed that night. So Jessica agrees to keep quiet and cover for Wilden and Red Coat beause Wilden had something big on her, perhaps the fragile patient was Charles and he knew the truth about Charles, Whatever happened to Marion has a purpose to this story. I think Jessica saw cece spying in a bush and after returning home she sees Ali through the window and doesn`t look impressed. I think that moment she figured what she had just seen was another game of Ali and Cece`s and was a hoax but then she sees Charles hit Ali with thr rock. She later pays Cece to keep quiet about what she saw because she didn`t want Cece to figure out Ali was dead and had her leave town. Wilden and Red Coat leave thinking they killed Ali. Cece is unaware of what happened to Ali but knows Bethany was killed, excepts Jessica`s payment and leaves town. As for Charles he found Bethany on the ground and most likely saw Cece lingering fleeing and because he recognized her from her Radley appearances assumed she was guilty of murder. When he hit Ali he thought it was Cece and Jessica covered for him to protect him. The next day he found sara who was running away and he took her and had her dress like Ali as a coping mechanism for what he did to Ali. Ali reaches out to Cece after that night and Cece returns to Rosewood in season 3 because with Mona`s confession of being -A and in radley she and Ali can assume she was Red Coat and it`s just Wilden they need to deal with. Cece was afraid of him but she was trying to confrim Mona was Red Coat before Ali could come out of hiding. This is why she went to visit Mona. She tells people she thinks Wilden was there that night to see ALi and she tells about beach hottie and insinuates Wilden was sleeping with Ali. Jason isn`t pleased with Wilden and Wilden is agravated with Jason for shooting his mouth of saying he was sleeping with a monor. Emily and Jason find the cape cod photo of Cece,Wilden and Ali in which Melissa took and this results in the Elevator accident. Someone didn`t want them to know about the connections. Melissa had bold faced lied to Spencer beforehand and stated although she did go to highschool with Wilden she didn`t really know him and of course Wilden denies sleeping with Ali but this is the duo who became the queen of hearts. Spencer was out with Wren when the elevetaor collapsed so if he is Chalres his hands are clean of the elevator failure and Wilden and Melissa had motives for that. Melissa was in Rosewood thus she called Spencer but wasn`t in the episode. My guess Jessica thought Wilden was involved and Paid Cece to off him as he was becoming a problem and to protect Jason. Jessica thinks Cece thinks she saw Ali get killed as a hoax but is unaware Cece knows otherwise.If Cece tells about the hoax she would be questioned about why she didn`t call the cops and explain she was blackmailed and questioned about her daughters whereabouts and made a suspect etc. Chalres isn`t pleased with what happened either but figures out Cece didn`t kill Bethany and stole the game from Mona and kicked her to the curb. Marlene said he stole the game from Mona but never said he stole it from Red Coat. Mona and Red Coat were partners so Red Coat is solo now and Charles stole the game to protect the girls and Red Coat became his rival. Sara was a runaway and Charles gave her a place to hide, I do think they became friends and Sara is his friend and Ali who gave him the birthday gift and is the black hoodie caught in the photo Aria has. She is not evil and wasn`t his prisoner but is helping him keep the liars safe. She is the one who kidnapped Mona and helped put her in the dollhouse. So if this is correct than Charles and Sara are protecting the liars while Red Coat is trying to harm them and using minions to help her. So with that in mind once Wilden is dead Jessica continues to cover for Charles who she believes killed Ali, she no longer has balckmail over her head by Wilden but she thinks Bethany`s death was a hoax anyhow. When she discovers Ali isn`t the girl in the grave she realizes it was never a hoax and with Ali alive her son killed no one so she goes to the hastings house to advised she can no longer cover for Red Coat and winds up dead and buried in the backyard. She went to see Melissa and wanted to make sure she didn`t know what Wilden knew before turning her in. Melissa makes perfect sense and her motive is on those tapes Ali stole from Ian`s laptop she so desperatley wanted back. I think the video she is so concerned about is video from the frat party Ian was at. Ian and Melissa were on a break and Ian was with some girl who ended up at the bottom of the stairs. The video can prove Melissa was present and since the liars were there they could piece together what really happened that night. What we know is Melissa went to see Ian the morning of Labor Day in a jealous rage thinking he was with Ali. She had a abortion appointment scheduled but miscarried before attending it. Ali stole the tapes from his laptop so the tapes Melissa wants back are of something yet to be seen. Jenna wanted these tapes back too but we know why and seen her and Toby`s tape. We know Ian thought he had a stalker during the time of the frat party. He thought it was Ali and so did the liars but Ali has never confirmed this. We know Ali wasn`t sleeping with Ian but was sleeping with Beach Hottie, liekly Wilden so no motive to be obsessed with Ian. Cece was framed for the incident and kicked out of Upenn. MElissa also attended Upenn. Melissa had the most motive to be the obsessed jealous girlfriend and the one to push the girl down the stairs. She is smart enough to fram Cece for it. A tape from that night would prove just that. We do see Melissa Labor day morning telling Ian if he saw Ali again someone would get hurt. The next part of her motive has to do with 2 weeks before Labor day when Ali had a fight and was given a bloody lip from a girl. Melissa fighting with Ali could be how she had the miscarraige. She hated Ali for it. She wanted to keep it but Ian wanted her to abort it, one year later Melissa couldn`t wait to get pregnant again and when Ian caught her telling Spencer she was trying Ian wasn`t pleased at all, Melissa claimed he was the one to break her heart and it confrimed he had dumped her but the why was never given. The liars only became targets after the body was found but Mona was original -A but when the girls got their hands on Ian`s tapes she approached Mona for a partnership. Mona had Ali`s diary and such but Melissa would have the access to his tapes. Her 1st priority was to get Ian back and sending a clip from that night of Ali had Ian running back to Rosewood. He recognized the footage and knew someone could place him with Ali. a text from -A and he`s asking Melissa for coffee and she plays all coy with he broke her heart bit and declines only to later accept. The liars get sent video of Ian and Ali from -A and he becomes their number one suspect. He begins to act odd so I think he suspects Spencer is the one toying with him and could be -A wanting him back with her sister out of guilt for kissing Wren. The liars find a tree stump with Ali loves Ian on it and evidence points to Ian until he obliges -A`s commands and excepts Melissa`s proposal to marraige and elopes with her, as soon as they are married the tree stump is burnt and Tobey becomes the cops suspect owning the sweter she was wearing and all evidence pointing to Ian vanishes and Spencer is left looking like a fool. If you watch back Melissa is then doing her damness to make sure she believes Toby killed Ali. Melissa was blackmailing Ian to get back together as -A. This brought Spencer and Toby closer together. So Melissa announces a pregnancy and the liars still believe Ian killed Ali at the end of season 1 Ian attacks Spencer but Ali pushes him off the bell but saw him crawl away. Spencer went back to the church to get Melissa`s cell phone and Ian showed up, he claimed he did get Melissa`s messages and Spencer afraid of him says think about Melissa and he mumbled it`s what Melissa would want. They both think eachother are -A at this moment and that`s why Ian attacked her and on the bell tower says to her it`s because I love Melissa but in his thinking Spencer is -A it`s said as isn`t that what you wanted? So season 1 Mona is tormenting the liars pretending to be Ali from the grave using her diary while Melissa was trying to get Ian back and using his videos to do so. Season 2 Garret found Melissa`s cell at the church and returns it to her, only person who had their hands on it was Garret. The liars are led to believe Ian is alive thus no body was found and Spencer gets her hands on Melissa`s phone and to make sure it was Ian she has him say the baby name picked out which was Taylor so they now know he is alive. Suspicious that Melissa is secretly meeting him Spencer comes home in 2x03 and asks Melissa if she`d been out and the playing the grieving Widow states she never left the house but Spencer notices her wet boots and wet Red Rain Coat and pulls out a ultrasound picture from the pocket. This proves she went to see Ian that night wearing a Red Rain Caot but we never see her wearing it. A week later Spencer goes to see Melissa in the barn and the door is conviently ajar with the shower running and a bag packed and ready by the door so she opens it and it`s a bag for Ian. Melissa is smart enough to know when being spied on and most likely clued in days before but she needed witnesses when she finds Ian`s body thus the liars follow her as she meets with Wren for her pain killer delvery, she needed someone to back her story and she goes into the Barn and finds Ian dead with a suicide note and confession made from -A messages. It is later revealed he had been dead for a week already and Melissa claims someone must have been pretending to send her text as Ian as his cell rings and Melissa grabs from Spencers bag. Melissa easlily could of placed it in her bag to back up her story. So of course that allows Melissa to yell at Spencer and drop the suspicion on her. The thing is we know Melissa left the house in a Red Rain Coat with an ultrasound in her pocket so if not to go see IAn than where did she go and why did she lie? This was a week before his body was found. At 1st Melissa refused to believe Ian tried to kill her but if she found out from him that he did and he would have seen Ali push him so he knows she is Alive so he is free to do what he wants cause he can`t be framed for her death if she is alive so he could of broke things off so she killed him that night. Spencer and Toby get closer and Melissa becomes the prime suspect as -A to the liars while Mona is doing whatever Red Coat aka Melissa tells her to do but the liars started to warm up to Mona near the end of season 2 and Mona got a text from -A to break up Caleb and Hannah so the plan was to have Mona kiss Caleb and fro Melissa to see it and see if they got a text. Indeed the liars did but they keep it from Mona making it clear she`ll never be one of them. She was ready to turn on Red Coat but that changed her mind but she had to fix what she did so with the heat on Melissa who was black swan needed Mona to take the heat off of her by revealing herself as -A to Spencer and to try and recruit her sister to the A team. Spencer declined and after fleeing the ball as black swan we later see Melissa outside MAya`s house as they drag out a body and then the final scene of Red Coat visiting Mona and Mona saying I did everything you told me to do. That`s just my theory summery on things I have expalnations to everything going forwrad but tired of writing..lol As far to why MAya was killed though I think it was so -A could get her out of the way so she could send in Paige to get close to Emily thus Paige was a minion at the time working for Red Coat but had nothing against the liars herself other then Ali but actually cared for Emily unaware of the bigger things .
