Friends of shooting victim Anna Holmes set up a trust fund for her children Monday while homicide detectives worked feverishly to find the woman's killer.

Holmes, a pregnant mother of three, was shot in the head at a Kearns video store. She died a short time later after giving birth Caesarean section to a fourth daughter.People wishing to help her children can donate to the Anna Holmes Children's Trust Fund at Benjamin Franklin Federal Savings and Loan Co., 5471 S. 4015 West, Kearns, UT 84118, where she was a manager.

Meanwhile, homicide detectives continued a process of elimination in their search for the gunman.

"We've eliminated a lot of people and a lot of vehicles," said detective Capt. Bob Jack said, adding that not suspect has been identified yet in the apparently unprovoked shooting.

The sheriff's office has set up a command post outside Voyager Video, 5448 S. 4220 West, where a robber shot Holmes, 31, 3845 W. Grouse Circle, point blank in the head for no apparent reason while her three daughters and three neighbor children stood in horror.

Holmes was more than eight months pregnant and was delivered of her fourth daughter minutes before being pronounced dead at 9:36 p.m. Friday at University Hospital, a hospital official said. The baby was listed in serious but stable condition Monday.

Officials have manned the post since the shooting and have been talking to residents and scouring the area for physical evidence to uncover leads in the case, Jack said.

A shirt found by a church janitor in a field near the video store and described by Sheriff Pete Hayward as blood-stained and fitting the description of the one worn by the gunman had not been laboratory-tested late Sunday, Jack said.

"We certainly hope it (test results) will tell us something, but we don't know what or how good the information will be," Jack said. "We can't overlook anything."

Jack would not comment on media reports that authorities have obtained fingerprints from a videocassette box apparently handled by the gunman. No other physical evidence of the incident has been discovered, he said.

Footwork, reports and other investigative efforts have been considerable, Jack said. Hayward has pledged to keep deputies in the area until the gunman is caught.

Witnesses have described the robber to authorities as a white man between 30 and 45 years old with gray hair and a sparse mustache. He was wearing a plaid shirt and faded jeans when he entered the store about 8:40 p.m. Friday.

After getting between $300 to $350 from the clerk and stuffing the cash in in a green canvas bag, he grabbed Holmes, placed a handgun against her head and shot her.

Sheriff's officials are also searching for a large white or light blue car, possibly a Buick, that witnesses said the robber used to flee.

Holmes' slaying was the fifth in Salt Lake County this month.
