WICHITA, KAN., JAN. 1 -- Police searched today for clues in the slayings of an accountant and his two daughters in the latest in a series of holiday family killings.

Mary Fager discovered her husband, Phil, 37, dead in their home Thursday, and police later found their daughters, Kelli, 16, and Sherri, 9, dead in the family's new basement hot tub.

Based on autopsy results, police Capt. John Dotson said Phil Fager died of two gunshot wounds to the back, Kelli was drowned and Sherri was drowned and strangled. He would not say how long the three had been dead.

Police said they knew of no motive and no suspects. Homicide Lt. Dave Williams said detectives were examining evidence and trying to locate people who may have seen the victims in their last hours.

Neighbors said the family had lived in the house since it was built in 1978.

"They kept their place immaculate," said Joel Pollack, who lives across the street. "Their kids were very nice kids. They were a lovely family."

Mary Fager returned home about noon Thursday after visiting relatives in Emporia and found the clothed body of her husband on the living room floor, police Capt. John Dotson said.

Fager had a chest wound, but it was not known if that caused his death, Dotson said.

After discovering her husband, Fager went to a neighbor's home. She was at the police station being interviewed by detectives about his death when she learned that police had also found the daughters' bodies, Dotson said.

The girls were found floating under the fabric cover in the water-filled hot tub. Neighbors said the tub had been installed recently.

Police Chief Richard LaMunyon said the victims may have been dead for 24 to 36 hours before being found.

The only thing missing from the Fagers' well-kept house in their affluent neighborhood was a 1983 Volkswagen Rabbit, which Williams said had not been located.

Police said that the home had not been ransacked and that no signs of forced entry were found. The front door was locked when Mary Fager arrived home, police said.

Fager was an accountant for Boeing Military Airplane Co. Kelli was a high school junior and Sherri a third grader.

The killings were the latest in a string of slayings involving families during the holiday season.
