How a murderous teen reacted to strangling his mom to death in their home is absolutely chilling

Teen calls 911, says he killed his mother, officials say

Jacob Taliaferro stabbed his mother Lorrie Demko in the chest and strangled her to the death with a rope on Monday, only to take a shower and watch TV before calling 911 at 5:02 a.m. and telling a dispatcher what he had done.

Taliaferro said the knife he stabbed his mother with was in the kitchen sink and that she had been dead "for a while."

The 17-year-old male shocked the safe Palmyra, Pa. neighborhood with his heinous crime.

Numerous neighbors and family friends came forward and said the accused murderer has had "a lot of problems," but that they never thought these issues would result in murder.

Melissa Hess, a friend of the victim, told Penn Live, "I don't know why – he didn't want to talk to her" and that she "tried to talk to him, but he didn't want to listen.

"[Jacob] had a lot of problems. But we never would have dreamed he would have gone this far," she said.

Another friend named Deborah Lanham said Demko's son "wasn't very social and kept to himself."

Deborah Herbe from just down the street reflected on how horrible Demko's death must have been.

"It's horrible. Her death had to be horrible and to open her eyes and see her son doing this to her had to be horrible," she said. "It's really hard to believe that something like this could happen. It's just sad."

Herbe said she believes Demko had two other children.

District Attorney David Arnold said he doesn't think "mental health" played a role here.

"I don't believe mental health played a substantial role," he said. "[But] when you do something like this, obviously something has gone a little wrong in your life."

Arnold also said he doesn't believe drugs were involved.

Taliaferro is being charged as an adult for criminal homicide and is being held in Lebanon County prison without bail.
