Incident

Captain Rocky Langlinais was shot and killed while trying to remove a suspect from a Greyhound bus at the Lafayette Bus Station on Lee Avenue. When officers received a tip that the man, who was wanted for criminal negligence, was on the bus due to arrive at 10:00 p.m., officers waited for the bus to arrive. The suspect was the last to exit the bus holding a shotgun wrapped in newspaper. He pulled out the gun and shot Captain Langlinais. The suspect was shot and killed by other officers. Captain Langlinais was transferred to Lafayette Memorial Sanitarium, where he passed away. Captain Langlinais was a United States Army WWII veteran and had served with the Lafayette Police Department for ten years.

Tributes

I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.
Captain Langlinais gave the Lafayette Police Department 10 years.
Thank you for your service to the Lafayette community, and for your service before it. Gone but never to be forgotten.
Rest easy, brother.
