Investigators in suburban Fort Worth are trying to piece together the history of a family targeted in a Christmas Day shooting that police believe was carried out by a relative dressed in a Santa Claus suit.
The names of the seven people found dead inside the Grapevine apartment, including the alleged gunman, were expected to be released Tuesday, police said.
Grapevine police spokesman Sgt. Robert Eberling said the shooter showed up in the costume shortly before gunfire erupted, and 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.
Eberling said investigators were assembling a "family history," and that the apartment was leased to a woman and her two children, one age 15 and the other either 19 or 20. He would not give other specifics.
"We're getting a clearer picture, but we're not ready to go on the record with anything until we find out from the medical examiner absolute confirmation of identities and the manner of death," Eberling said.
Autopsies of the shooter and the victims were being done Monday by the Tarrant County medical examiner.
Roger Metcalf, a spokesman for the medical examiner's office, said the victims have been tentatively identified, but the office couldn't confirm the names because the state driver's license fingerprint database wasn't available on the holiday.
"In addition, we need to locate next of kin before information can be released, and our investigators are working on that as well," Metcalf wrote in an email to the AP.
Late Sunday evening, police intently searched a sport utility vehicle parked outside the apartment. The vehicle is registered to a man who listed his residence as a home two miles away in the neighboring suburb of Colleyville.
Thomas Ehrlich, who lives near the home in Colleyville, told the AP he heard from neighbors that police went to the house Sunday. He said he believed the man and woman who once lived there were estranged.
Records show the couple had financial problems and that their home, most recently valued on the county tax rolls at $336,200, had been sold in 2010 at a foreclosure auction _ although it appeared the man was still living there.
"I actually saw him out doing yard work just last weekend," Ehrlich said.
Spa manager Leah Langford said she became concerned when the man's wife didn't show up for work Monday at the business where she had been employed for four years. Langford said she got no response when she called the woman's cell phone, nor could she learn anything when she went to the Colleyville home and the Grapevine apartment.
"For somebody who's always early to work and who never misses a day of work, we expected the worst," Langford said.
The shootings Sunday were the first homicides in Grapevine in more than a year and a half.
Police and firefighters rushed to the Lincoln Vineyards complex about 11:30 a.m. after receiving a 911 call in which no one was on the other end of the line. Because no one responded on the phone, police went into the apartment, located at the back of the complex. They found the seven, aged 15 to 60, dead.
Many of the nearby apartments are vacant, and police said no neighbors reported hearing anything on a quiet Christmas morning when many people were not around.
