Detectives spent hours at the Ashtree apartments on Willow near Ashlan following the discovery Friday night.
They say they found a man's body inside one of the units around 6 p.m., but detectives had to wait until just before midnight for a search warrant so they could start collecting evidence.
The incident started as a welfare check. Once officers noticed a man dead in the apartment, they found it suspicious enough to investigate it as a homicide.
Behind yellow crime scene tape, detectives from the Clovis Police Department spent hours talking to potential witnesses and surveying the outside of this apartment.
Just before 6 p.m. Friday night, someone from Community Regional Medical Center called officers, asking them to do a welfare check here.
Janet Stoll-Lee with Clovis Police said, "They did not have a search warrant to get in, therefore they got a key from the manager, opened the door ad found a deceased man inside the apartment."
Officers checked to make sure no one else was inside.
Once the area was cleared, they had to leave.
By 10 p.m., investigators were still waiting for permission to go back and collect evidence.
"Currently, we're waiting for a search warrant to be signed so we can go in and see exactly what happened."
Officials will not say who the man is or whether his body showed obvious signs of trauma.
Meanwhile, neighbors tell Action News two men in their twenties moved into the apartment about six months ago.
Michael Castillo lives just a few doors down. Castillo said, "I didn't hear anything. Just the normal evening. Cold, quiet dark, but nothing."
Other neighbors say they rarely see police activity within the complex, which makes Friday's scene all the more frightening.
Barbara Lynch said, "Yeah, I was very surprised to see all this, because it's a quiet complex. We don't have any trouble back here at all ever."
