Police are trying to locate a Utah State Prison inmate who walked away from a halfway house Tuesday.

Daniel R. Troyer, 29 - whom police have questioned in connection with the suspicious death last week of an elderly Salt Lake woman - left the Bonneville Community Center for a job interview and never returned, said Juan Benavidez, spokesman for the state Department of Corrections.Troyer, who has been imprisoned since September 1985 for a house burglary conviction, was scheduled to be paroled in March 1989.

Salt Lake police detectives questioned Troyer in connection with the mysterious death of Ethel Luckau, 88, whose body was discovered by relatives last Thursday in her home, 357 E. 17th South.

Troyer, who served time in prison in the early 1980s for the attempted rape of an elderly woman, told officers he had been within a block of Luckau's home on Aug. 15, the last day Luckau was seen alive, said homicide squad Sgt. Don Bell. But there was nothing else to indicate Troyer had anything to do with her death, so police did not detain him.

The state medical examiner's office has been unable to determine a cause or manner of Luckau's death. There are some signs, however, that she could have been assaulted. The results of additional laboratory tests are due sometime next week and may shed new light on the death, said detective Lt. Mel Shields.

Troyer was also questioned in July 1985 in connection with the strangulation of 83-year-old Drucilla Ovard, whose body was found in her home at 1457 Logan Ave., Bell said.
