Wisconsin's Most Wanted: Oscar Rash sought for shooting after argument

MILWAUKEE - An argument on a bus led to a shooting outside of it, and investigators said the man who pulled the trigger is on the run.

"He’s a dangerous dude," the U.S. marshal on the case said. "He needs to be off the streets." 

Investigators said, in February 2023, Oscar Rash boarded an MCTS bus and got into an argument with another man. Investigators said Rash pulled out a gun, and when the men stepped off the bus at Richards and Capitol, the situation got even more heated. The marshal said Rash fired two shots at the victim, hitting him in the legs.
