A man fatally stabbed on south State Street, a body pulled from the Jordan River and a sex-related slaying were on the agenda Friday for detectives in two Salt Lake County law enforcement agencies.

The latest killing, Salt Lake County's 15th this year, occurred early Friday. The body of Darrell N. Webber, 39, 1860 W. Homestead Farms Lane, was discovered in a parking lot at 4060 S. State. He had been stabbed in the chest, said sheriff's Capt. Bob Jack.A sheriff's lieutenant found the body about 3:20 a.m. after a truck driver reported to the sheriff's office that a man had just admitted to him that he had stabbed someone to death.

The suspect was last seen running west on 4060 South. He was described as Hispanic, about 25 years old, 5 feet 8 inches, about 155 pounds.

Meanwhile, the sheriff's office has identified the girl whose body was found 7 a.m. Thursday outside an office building at 4511 S. Sixth East.

Felicia Pappas, 17, 4652 S. Seventh East, was raped and strangled on a small lawn east of the building. It is believed the girl was walking home from South Salt Lake about 1 a.m. when she was attacked. No suspects have been identified, Jack said.

Salt Lake Police detectives on Friday were still trying to identify the body of an Asian man found in the Jordan River across from the Jordan Park International Peace Gardens.

A Salt Lake Housing Authority employee discovered a man's body about 11 a.m. Thursday submerged in a few feet of water just off the west bank at approximately 10th South.

Detective Lt. Norm Thompson said the victim was nude except for a blanket that had been tied to his neck. A rock had been placed in the blanket, apparently to sink the victim.

Investigators believe that whoever dumped the body must have done it at night because the body came to rest on a shallow underwater ledge close to the bank. "Whoever put him there probably assumed he went into the main portion of the river."

Thompson said the victim suffered a head injury that looks like a gunshot wound. An autopsy was under way Friday morning.

The victim was described as about 20, medium height, with a slender build. No jewelry, identification or other personal belongings were found.

The lieutenant said the victim had been in the water for 24 to 48 hours. It was unknown where the victim was killed.
