Mission ? Mission police say a Merriam man shot and killed his 52-year-old brother outside an office building and then later killed himself.

Mission Police Capt. David Moloy says 58-year-old Robert J. Pruitt shot his brother, Todd Pruitt, of Shawnee, early Thursday in the parking lot of an office building. Todd Pruitt died later at a hospital. Moloy says several people witnessed the shooting.

Moloy says that about five hours after the shooting police found Robert Pruitt had taken his own life in a park in neighboring Kansas City, Mo.

The Kansas City Star reports that Todd Pruitt worked for Kansas University Hospital, which issued a statement expressing condolences to the employee and his family.

Moloy says the motive for the shooting is unclear.
