gun used in what police called a "thrill kill" could be linked to other random acts of violence, they said.Kansas City detectives have the shotgun.They know what shootings it's linked to, but they can't prove who pulled the trigger, so they can't file charges.And that is proving extremely frustrating for them. "The shotgun -- (that Fabian D. Brown Jr., and Raphael Willis used the shotgun to kill Robert Wynn Osborn, 43, in November of 2005) -- kept coming up in several other shootings that we had," said Sgt. Richard Sharp.Osborn was riding his bike home from his job as a grocer when Brown, 23, and Willis, 22, shot and killed him. They admitted it was a thrill kill and both men were sentenced to 15 years in prison."They're shooting at people just to be shooting at people. They had really no valid reason for doing it," Sharp said.Sharp said he believes Brown and Willis were part of a gang that shared the shotgun and used it in five or six other unsolved thrill shootings."We basically know who was at the scene. We basically know everything that happened, but the one instance that we don't have is who actually pulled the trigger," Sharp said.
Ballistics matched the shotgun shells to a July 2005 shooting at a junkyard near East 63rd Street and Swope Parkway. Gunmen shot and killed two guard dogs, then shot at the security guard, who was in his 90s.Two weeks later, police said the gunmen fired the same shotgun from the Sni A Bar Bridge at a motorist driving down Interstate 435.They wouldn't give out details in the other unsolved thrill shootings but they said the trend worries them."It makes it extremely dangerous for everybody because anybody can be a target," Sharp said.Police can only solve the unsolved shootings if someone comes forward and identifies the shooter, they said.
