Gunman leaves name, address at scene.

From Breitbart:

KENTWOOD, Mich. (AP) - Police in Michigan say a man who held up a gas station left behind a major clue—a piece of paper bearing a name and address. Police said they went to the address and arrested a 42-year-old suspect. The holdup took place Tuesday at a Speedway station in the Grand Rapids suburb of Kentwood.

Police told The Grand Rapids Press the robber told the station clerk he had a gun. He appeared to be holding a weapon beneath a piece of paper.

After getting cash, the man dropped the paper and ran when the clerk made a move toward him.

Officers said the address on the paper was for a Grand Rapids apartment. They arrested the suspect when he arrived about an hour after the robbery.

The gun turned out to be a homemade fake.
