Calgary police have charged a man with second-degree murder in connection with the death of a man at a southeast home on Saturday.

Police were called to a home in the 100 block of Auburn Springs Close S.E. just before 11:30 p.m. and found a dead man at the scene.

Investigators believe that the suspect and the victim met earlier in the day at the victim's residence and that both lived in the same neighbourhood.

"We believe that they met for the first time earlier in the day, they were neighbours, they spent some time at the victims residence and then transitioned over to the suspects residence," said CPS S/Sgt. Doug Andrus.

They believe the pair went to the suspect's residence in the evening where an altercation took place resulting in the death of one man. The other man was taken into custody at the scene without incident.

Nicholas Rasberry, 30, has been charged with second-degree murder and will appear in court on Wednesday.

CTV News has learned that the victim is Craig Kelloway, a popular teacher at  David Thompson School.

The CBE has sent the Critical Incident Response Team to the school to help students and staff deal with Kelloway's death.

Police say alcohol was involved in the incident and that the suspect is not known to them.
