An elderly grandmother woke up in her Dallas home Tuesday to find her daughter and granddaughter dead, along with the granddaughter's estranged husband, police said.

Police are calling the three deaths a double murder-suicide.

The estranged husband of Janice Hill, 24, is the suspect in the killings, Dallas police spokesman Sgt. Gil Cerda said. Keith Hill, 26, was found dead in the home with a rifle by his body. There was no sign of forced entry.

Janice Hill and Jeanne Carroll, her 52-year-old mother, were also found dead in the home when Hill's elderly grandmother woke up around 1 p.m. Tuesday. She is in her 80s, hard of hearing and never heard the rifle shots, Cerda said.

Yellow police tape surrounded the ranch-style East Dallas home, located on a street next to Eastfield College, a Dallas community college. Crime scene technicians and medical examiner's personnel entered the house with stretchers, at one point loading a black body bag into a van.

About 100 yards south of the home, Keith Hill's vehicle was hooked up to a tow truck to be carted away. Police said they believe he parked there, walked up the residential street with his rifle and was let into the home early Tuesday.

Janice Hill was assaulted by her husband in Grand Prairie on Oct. 9, Cerda said. Keith Hill was arrested on Oct. 23 and she sought a restraining order five days later.

Police were at the home as recently as Sunday. Janice Hill called police, saying she has been receiving harassing phone calls from an unknown person whom she believed was her husband. The caller never spoke, Cerda said.
