ALBUQUERQUE, N.M.>> Authorities in Albuquerque discovered three people had died after an off-duty state parks law enforcement officer spotted a person lying in the street and police followed a trail of blood inside a home where two people had been shot, police said Thursday.

The person found in the middle of the roadway appeared to have been stabbed and ultimately died, Albuquerque police spokesperson Gilbert Gallegos said.

Inside, officers found two people with fatal gunshot wounds. Neighbors had reported hearing the sound of gunshots earlier that morning.

No identities were released.

Detectives talked to a man who was locked in a room at the house and don’t believe he was a suspect, Gallegos said. It’s unclear if the man was wounded.

Detectives were trying to determine the relationship among the people involved. They filed search warrants for the home.
