A Kansas City man was sentenced Wednesday to 18 years in prison after he pleaded guilty earlier in the day to fatally shooting an off-duty Lee's Summit police officer during a crowded party in August 2017 at a Westport restaurant in Kansas City.

The trial for 23-year-old Sean Steward had started Tuesday at the Jackson County Courthouse in Kansas City. He pleaded guilty to second-degree murder, first-degree assault, two counts of armed criminal action, unlawful use of a weapon and unlawful possession of a firearm.

A woman also was injured in the shooting, which happened after a man Steward was with struck another man in the middle of an evening crowed at Californos restaurant. Multiple witnesses had identified Steward as the shooter, according to court documents.

A judge sentenced him to 15 years each for the murder and unlawful-use convictions, five years each for the armed criminal action convictions and 10 years for the assault – all to run concurrently. A three-year sentence for unlawful possession will run consecutively.

In a statement, Lee's Summit Chief of Police Travis Forbes thanked prosecutors and Kansas City Police for their time and resources in working the case.

“Obviously, there is no amount of justice that will account for the life that a man like Thomas Orr lived,” Forbes said. “His contributions to our community will never be forgotten. Like many victims of this senseless type of crime, we wish we could have him back.

“My thoughts today are with Thomas' family, our community and our family at LSPD.”
