Monday to piece together a family history after a man dressed in a Santa Claus suit apparently shot six relatives and himself on Christmas.
Grapevine police spokesman Sgt. Robert Eberling said the shooter showed up in the costume shortly before gunfire erupted and that the family appeared to have been opening Christmas presents. Police responding to a 911 call found four females and three males dead. They also found two handguns.
"We think he was just inside there celebrating Christmas with the rest of them and decided for whatever reason that's how he's going to end things," Eberling told The Associated Press.
Investigators worked through Sunday night and into Monday morning, meticulously searching the apartment where the bodies were found, along with vehicles parked outside. Police said they believe the victims were related, though some were visiting and didn't live in the apartment.
