Southwest City police officer's manslaughter conviction upheld by court

The Missouri Southern District Court of Appeals upheld the involuntary manslaughter conviction of former Southwest City police officer Brian Massa earlier this month.

Massa was found guilty by a Barry County jury, which heard the case on a change of venue from McDonald County, in 2011.

Massa shot Bobby Stacy, 26, Gravette, Ark., to death March 28, 2010 during a traffic stop. Massa was arrested after a Missouri Highway Patrol investigation revealed that the evidence did not match Massa's version of how the shooting occurred.

He is serving a three-year prison sentence.
