HOUSTON (CW39) — There was an officer-involved shooting at a group home for the mentally ill in west Houston on Saturday night.

Houston police said shots were fired after the distressed patient pulled a knife on officers.

It happened on the 1300 block Riverview Court around 11:45 p.m. when police received a call that one of the residents was having a mental health crisis and threatening other residents with a knife.

Officers arrived and told the man to put the knife, but officers said the man started to move toward one of the two officers.

That’s when one officer fired at him. The man, identified as Bryan Stuart Cornitius, 38, was taken to a local hospital and was last reported in critical condition. Cornitius was also charged with two counts of aggravated assault of a public servant.

Officers are now investigating the residence, which they believe is some sort of group home. An investigation is underway into the incident, as well as if the residence is an illegal group home or not, police said.

The officer who shot the suspect has been with HPD for one year and is assigned to the South Gessner Patrol Division.

As is customary in officer-involved shooting incidents in the city limits, the incident is being investigated by the HPD Special Investigations Unit, the Internal Affairs Division and the Harris County District Attorney’s Office.
