Salt Lake police remained tight-lipped Monday about a body found inside an apartment, but they are calling the man's death a homicide and say they do have some leads they are following.

"There were wounds to the body," was all the information Salt Lake police detective Jared Wihongi would release Monday about how the victim was killed.

The body of 21-year-old Jonathan Mardoniz was found inside a second-floor apartment at 1340 S. 200 East about 10:30 p.m. Sunday.

"We do have some leads, but we're also asking for any information the public might have," Wihongi said.

According to other residents of the small apartment complex, some speaking to the Deseret News through an interpreter, Mardoniz was staying in the apartment where his aunt and nephew lived. They were reportedly in Las Vegas over the weekend and drove home Sunday night. For an unknown reason, the aunt had a bad feeling that something had happened and drove an average of 85 mph all the way back, said Gil, a tenant who lives next door.

Some tenants said the last time they remembered seeing Mardoniz was about 4 p.m. Sunday while he was sitting on the steps of the apartment complex talking on the phone. After that, several residents reported seeing the door to his apartment wide open for a long time, but there was no sign of Mardoniz or anybody walking in or out.

A man who lives in the same apartment complex and knows the family well went to the second floor and shut the door of the apartment but did not go inside, according to neighbors.

When Mardoniz's aunt got home, she found his body on the floor, Wihongi said. Initially there were no signs of foul play, but the death was ruled a homicide after a closer inspection at the scene by the state medical examiner, he said.

Neighbors said they did not hear anything out of the ordinary Sunday evening. Some said they were shocked to learn what had happened, noting that there never had been any trouble from that apartment.

"I'm pretty surprised. (That apartment) is one of the quietest ones," said Chris Hayes, who also lives in the complex. "It's crazy. I stayed home from work today because my girlfriend — we have a newborn baby — didn't want to be left alone."

Detectives Monday did not release any possible suspect information.

Anyone who may have seen Mardoniz or something suspicious is asked to call police at 799-INFO.
