UPDATE: The man killed in a stabbing Thursday has been identified as Charles Gregory Register, 42, Colorado Springs police said Friday.

They said the investigation is continuing.

Earlier story:

Colorado Springs police say a 42-year-old man died in a stabbing and a 31-year-old man was injured Thursday morning at a home near the intersection of Austin Bluffs Parkway and Nevada Avenue in Colorado Springs.

When police arrived about 6 a.m. at 4615 Mallow Road they found two wounded men, one of whom had died.

The injured man was taken to a hospital and released Thursday afternoon, a police spokesman said. The nature of his injuries were not divulged.

The men's names have not been released.

Investigators entered the house about 8:45 a.m. wearing black jumpsuits with the words "homicide detective" on the back.

Antonio Anaya, who lives at 4604 Mallow Road, said he came home from work at 6 a.m. Thursday and there were about a half-dozen police cars surrounding 4615 Mallow.

"I was nervous," Anaya said. "Something was definitely wrong."

Anaya, 20, has lived at the home his entire life with his grandparents, he said. The man, who delivers newspapers, said six to eight men, mostly in their 20s, have lived at 4615 Mallow for about a year.

Anaya said he and his grandparents have heard arguing and fighting coming from the house about 50 yards across the road. According to Anaya, one of the residents "has an attitude."

"My grandma said she has heard him make threats to people who live with him," Anaya said.

If Thursday's death is ruled a homicide, it would be the 21st in Colorado Springs in 2012. There were 28 by the same time in the city in 2011.

The El Paso County Coroner's Office scheduled the autopsy for Friday morning.
