Authorities responded to the 1100 block of North Alma Avenue just before 1 a.m. Wednesday. They were called by a woman who said her adult son was possibly suicidal. There was also a report of a gunshot before deputies arrived.
Investigators surrounded the home but were not able to make contact with the man. Some nearby homes have been evacuated as a precaution.
A SWAT team eventually threw tear gas canisters into the house at about 8:45 a.m. and entered the home, but the man was not there.
The tear gas canisters started a small fire at the house that was quickly knocked down.
If you have any information regarding this incident, you're urged to call Crime Stoppers at (800) 222-TIPS or (800) 222-8477.
