Police in Missouri asked for the public's help Wednesday to find the person who shot and killed a man in front of his 10-year-old daughter.

Jake Brantner, 39, was gunned down in a Raytown shopping center parking lot Sunday at about 8:30 p.m., according to Fox 4 KC. Kansas City police said there were plenty of people who witnessed what happened, but so far there have only been three calls to the department's tipline.

"There was a little girl sitting in the passenger seat crying and a man outside the car ... outside the car bleeding," an unidentified witness told Fox 4 KC. She said she didn’t want to be identified because the gunman hasn’t been arrested.

The witness said she was in the parking lot when she heard several gunshots. She told the station that she drove over to where the shots came from and found the man and the child.

“I asked her to unroll the window and she did. I asked if she was ok, she was, she was asking for her dad. I didn't want to say anything about her dad because from where she was sitting I didn't think she could see him lying there," the witness said.

Friends of Brantner told KCTV that the incident was likely a Craigslist deal gone wrong. Brantner reportedly was in the parking lot to sell someone a handgun, but police haven’t confirmed that information.

Daniel Holdcroft, a long-time friend of Brantner, told the station he was a family man and well-known in the local car racing community. He said Brantner took a buyout from General Motors to start his own body shop that specialized in race car fabrication.

Police have not released any description of the alleged gunman and are urging anyone with information to call the TIPS Hotline at 816-474-TIPS.
