A 911 call shortly after noon Tuesday led police to a murder that came after a woman who already feared her boyfriend tried to get him our of her life.
"I need the police, I just shot my girlfriend," Gregory Twyman told the 911 operator.
Twyman then told the operator that he used a shotgun to kill Jamica Woods and that he would be waiting on the front porch of his Rokeby Road home in East Fallowfield, Chester County, Pa. for police to arrive, according to an affidavit of probable cause.
Police officers responded minutes later and found Twyman sitting on the front porch, smoking a cigarette while he spoke to 911, according to investigators.
Officers went inside to find Woods dead of multiple gunshot wounds. The shotgun was also found inside, according to police.
Chester County District Attorney Thomas Hogan called it a "premeditated and cruel."
"This was not an argument, this was a pre-planned execution," Hogan said.
Hogan said that Twyman took his time to reload the shotgun to deliver a second shot.
Twyman, 44, told police that after weeks of fighting he decided to shoot Woods, 37, with shotgun shells he bought "last week at Walmart."
Police say Twyman predicted the shooting on his Facebook page. The day before the homicide police say that Twyman made his Facebook profile photo a shotgun shell and the banner photo of his own shotgun, according to the affidavit.
Twyman told a friend that threatened to report the photos that it was "gon be too late," according to investigators.
Investigators say the Woods took an emergency protective order against Twyman last December but that she for whatever reason never signed a permanent order of protection.
She had taken put his clothing on the curb and was in the process of kicking Twyman out when he killed her, according to investigators.
Twyman was charged with murder and related charges and sent to county prison without bail.
