A Springfield man is undergoing psychological testing Thursday after grabbing a gun and opening fire in his home.
SPD officials say the man fired at least 20 shots in his home, claiming that he thought someone was trying to break into his house in the 900 block of West Mount Vernon.
An investigation by police found no evidence of an attempted burglary in progress.
At least two surrounding properties were hit by stray bullets and police are investigating to find other damage from the shooting incident.
The man has not been identified by the SPD, and no one reportedly was injured in the incident.
