Previous Report:

SCOTTSDALE -- Two men are in dead in Scottsdale and police are trying to figure out if and how their deaths are connected.

Police have more questions than answers in the situation.

All police know for sure is that one of the deaths was self inflicted. The other is a mystery.

This all started when a family filed a missing-person report for a 48-year-old man Saturday morning. According to the family, the man, identified as Paul Zimmerman, had not been seen since Thursday.

While there was no evidence of foul play at the time, the family was concerned that they had not heard from Zimmerman in two days.

Police located Zimmerman's truck parked on a Scottsdale street Monday morning. Information in the truck led them to a nearby home in the area of 93rd Street and Sweetwater Avenue.

Officers spoke to a man at that home. When the man went back inside to get some identification, officers heard a single gunshot from the backyard. Police searched the home. On the back patio, they found the man dead of a self-inflicted gunshot wound to the chest.

Evidence in the home led them to a construction lot about 1/2 mile away. There they found a body of a man wrapped in a tarp. Detectives are working to identify that person.

Investigators have not figured out how the two men are connected, nor have they positively determined if either of the dead men is Zimmerman.
