TUCSON (KGUN9-TV) - Tucson police are actively investigating a homicide with one man dead that happened on the west side Saturday morning.
Officers responded to a call reporting a shooting around 1 a.m. at 1607 Highland Avenue.
According to TPD, when officers got to the scene they found two men with "obvious signs of gunshot trauma."
Both men were treated at the scene and taken to a nearby hospital with life-threatening injuries.
Peter Ortiz, 25, was pronounced dead several hours after arriving at the hospital.
Officials say the second man is now stable with non-life-threatening injuries.
"It's a very sad and unfortunate thing to happen - our heart goes out to the victims and all parties that may be involved," says a man who chose to not be identified.
Detectives from the Tucson Police Gang Unit responded to investigate the incident and determined that just before the call came in, four uninvited guests arrived at a house party and tried to enter the home. They were told they were not welcome to the party and could not enter.
Police say the subjects then fired several gunshots into the air and then at partygoers, striking two of them.
The subjects then left the scene.
Witnesses say the subjects appeared to be gang-affiliated. They were described as four men, possibly Hispanic.
There are no suspects in custody at this time.
Officer Chris Hawkins with TPD says in 2017 there has been 33 homicides.
In 2016, there has been 21 homicides to date and 30 for the entire year.
