A convicted killer is now accused of shooting and killing his girlfriend on Christmas in Maryland, police said.

Around 6:30 p.m., officers from the Hagerstown Police Department in Maryland responded to a home for a report of a gunshot victim. The victim was identified as Tristen Shifflet, 37, and she was taken to the hospital, where she died.

Investigators determined Shifflet’s boyfriend — Justin Kyle Marshall, 34 — shot her in the neck during a dispute, according to Hagerstown police.

Marshall fled before police arrived and he was arrested around 2:45 a.m. in nearby Berkeley County, West Virginia, according to Hagerstown police.

Marshall was convicted of murder in 2004 in a homicide in Hagerstown and had been out of prison for two years, police said.

He had a warrant out of Pennsylvania for assault for an incident involving Shifflet as well, police stated.

The couple had a child together and child services took custody of the boy, according to police.

Marshall was charged with first-degree murder and other counts related to the Christmas incident, police stated.
