TARPON SPRINGS — A man who committed suicide after killing three people early Tuesday shot his victims multiple times and hunted one woman down as she hid in a bedroom closet, police said.
Officials on Wednesday identified that victim as Mara S. Shuman, the live-in girlfriend of Michael Schriebman.
Schriebman, 53, and his mother, 75-year-old Sarah Bricker Schriebman, also were shot in the home the family shared at 1407 Ironworks Lane.
The shooter, police said, was Michael Schriebman's nephew and Sarah Schriebman's grandson, Louis E. Schriebman, 21, who also lived at the home.
Michael Schriebman was shot twice in the back, twice in the chest and once in the head. His body was found in the master bedroom doorway, police said.
Sarah Schriebman, shot twice in the head, was found on the kitchen floor.
Shuman was shot twice in the chest and once in the head, police said. Her body was found in the bedroom closet, its door open.
Reached by phone Wednesday, Shuman's stepfather said she has two college-age sons at the University of Miami. He said it was too soon for the family to comment further.
Police found three guns at the house. A .38-caliber Ruger was in Louis Schriebman's lap, presumably the gun he used to shoot himself in the head. They also found a .357-caliber Smith and Wesson and a .45-caliber Glock. Police said they believe Louis used both in the killings.
According to police, the rampage started when Louis set fire to his uncle's gun shop, Silver Bullet Guns at 914 S Pinellas Ave., about 1:30 a.m. Tuesday. Louis worked at the shop with his uncle Michael.
Less than 10 minutes later, police were notified of an alarm going off about 2 miles away at 1407 Ironworks Lane. Officers found Louis and the other victims already dead.
Tarpon police Chief Robert Kochen said a motive for the killings has not been determined.
"We haven't gotten that far yet," Kochen said Wednesday. "But any time a kid breaks into a house and shoots people, he probably wasn't happy with someone."
Friends and neighbors reported a long history of bitter arguments between Louis and Michael. And the family may have been roiled by the arrest of Louis three days before the killings after a Pasco County deputy pulled him over and found a gun illegally concealed on his body and a pipe containing marijuana residue, according to reports. Police also found he was concealing morphine pills.
The fire Tuesday destroyed Michael Schriebman's gun shop and two adjacent businesses. A spokesman with the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives said investigators were still trying to determine if all the guns in the shop inventory were accounted for.
Michael, a licensed gun dealer, had two previous misdemeanor convictions for marijuana possession. He pleaded guilty in 1981 to felony burglary, but adjudication was withheld.
It is illegal for a convicted felon to possess a firearm in Florida, but when adjudication was withheld in the burglary case, Michael was eligible to obtain a federal firearms license, said Chris Sharp, spokesman for the ATF Tampa Field Division.
