A 54-year-old Good Samaritan trying to catch thieves who ran off with a Starbucks tip jar after the suspects hit him with their car died Wednesday, the St. Louis Post-Dispatch reported.

A woman described as being between 16 to 19 years old walked into the Starbucks around 3 p.m. Monday and bought a drink, and walked out to the parking lot. The 20-year-old man she was with grabbed the tip jar and ran, the newspaper reported.

Roger Kreutz, who police said was a regular customer, saw the incident and ran after the man. He died about 1:30 a.m. Wednesday.

Police were seeking information about the suspects from the public in the investigation that turned from an assault to a homicide after Kreutz died, Crestwood Police Chief Mike Paillou said.

Paillou asked the couple who ran over Kreutz to come forward. "There's two sides to every story," Paillou said. "We need to talk to the suspects."
