VALLEJO (CBS SF) — A daughter, mother and her boyfriend were found dead early Tuesda morning in Vallejo in what police say looks like a double-homicide-suicide.

Jackson apparently shot his 53-year-old girlfriend and her 14-year-old daughter before shooting himself with a shotgun.

“It’s tragic,” Capt. Jason Potts said.

Police said a 12-year-old girl found her mother and sister wounded in the living room, and after seeing Jackson, she fled the home, called 911 and ran to a neighbor’s house for help.

When officers arrived, the girl told police that Jackson shot her mother and sister. Officers later found Jackson, his girlfriend and the 14-year-old unresponsive.

Police said Jackson had more than one criminal conviction for crimes such as drug sales, assault with a deadly weapon on a police officer, DUI, and he had been arrested for misdemeanor domestic violence on March 8. Jackson was prohibited from having a gun, according to police.

Officers continue to investigate the slaying. The names of the victims will be released by the Solano County coroner’s office once the victims’ families have been told.
