Further details known about the incident

ALAMOSA — In response to a report of possible shots fired, the Alamosa Police Department responded to the 200 block of State Avenue at approximately 10 p.m. on Tuesday night.

Upon arriving on the scene, officers found the body of a deceased man who had been shot. He was later identified as John Cossel, 58, of Monte Vista.

A female person of interest, later identified as 57-year-old Kawanna Nelson, of Alamosa, remained on the scene and cooperated with the investigation.

According to arrest documents obtained from the Alamosa Clerk’s office, Nelson and Cossel were close friends and had had a brief altercation over him wanting the keys to his car and Nelson being concerned about his ability to drive. Cossel then left her apartment.

Nelson, who said she suffers from PTSD due to a previous violent incident, said Cossel then returned to her apartment and was banging on the door yet did not identify himself when asked to, twice.

She says she opened the door, while holding her 9 mm Smith and Wesson, and Cossel came inside and “went at her." She then shot him, once, not realizing that the man she shot was John Cossel.

Nelson was taken into custody, subsequently charged with second-degree homicide and transported to the Alamosa County Detention Center. She appeared in court on Wednesday afternoon for a hearing on advisement of charges.
