Alison DiLaurentis (Sasha Pieterse) may be back from the dead, but the same can't be said about her mother, Jessica DiLaurentis (Andrea Parker) who was murdered and buried alive on Pretty Little Liars. Season 5 promises to probe the murder mystery.
Show runner Marlene King dished to TV Line on March 19 about what will be the big mystery of Season 5: Who killed Mrs. DiLaurentis?
"Definitely," said King. "It's a lot of things, actually. Who would she have been protecting? Who would want to bury her? Who wanted her dead?"
In the Season 4 finale we discovered that it was Mrs. DiLaurentis who buried her own daughter. Alison revealed to the Liars what happened the night of her fake death: She was hit over the head with a rock while walking back from the Liars sleepover. Her mother was watching from the window. The next thing she remembered is Momma dearest burying her while she tried to tell her she was still alive! Her mother didn't listen. Later, Mrs. Grunwald pulled Alison from the grave.
It is still uncertain why Mrs. DiLaurentis would bury her own daughter Alison instead of searching for the killer (or calling the police). It is possible that her mother wanted to protect whoever nearly murdered Ali, according to Wetpaint.
Season 5 "EscApe From New York" premieres on ABC Family June 10.
