KANSAS CITY, Mo. -- A young mother was gunned down over a few pairs of shoes, police said.

More than a year after Victoria Franklin was killed in what police believe was a failed robbery attempt, her killer is still on the loose.

Kansas City, Mo., Police Department Detective Joe Marinella said, "She was just trying to earn extra money and she ends up dead."

Franklin was shot and killed near East 37th Street and Garfield Avenue on March 17, 2007.

Franklin had a side business selling shoes. She got a call to meet a man who claimed he was interested in buying some shoes, police said. Franklin and a friend showed up and were talking with two men when two others approached her car from behind.

Police said Franklin must have seen them pull a gun, because she hit the gas and was driving away when one man fired.

The shot hit Franklin in the side and killed her.

The would-be robbers ran away empty-handed, police said.

Police believe all four men were working together.

Witnesses have been able to give investigators information, but nothing that has made it possible for police to catch the shooter.
