Kansas City, Mo. ? Prosecutors have charged a Kansas City man in a bank robbery he was providing information on in an attempt to collect a $5,000 reward.

Daniel D. Salazar, 19, of Kansas City, faces one count of attempted armed bank robbery. Two Kansas City brothers, James E. Bowman, 38, and Jimmy J. Bowman, 40, also were charged Thursday in federal court with attempted armed bank robbery for the same incident.

“Mr. Salazar tried to cash in on the reward for his crime, but we decided to reward him in a way he didn’t expect,” U.S. Attorney Todd Graves said in a statement.

Prosecutors offered the reward for information leading to the arrest and conviction of those responsible for an attempt to rob a Bank of America branch on May 12. Three armed men confronted a janitor as he arrived at work that morning, forcing him to let them in and then ordering him to open the vault or teller’s drawers.

Prosecutors said Jimmy Bowman forced the janitor at gunpoint to open the door to the bank as James Bowman and Salazar approached; they were also carrying handguns. When they realized the janitor had no access to any money, they left.

An affidavit filed by prosecutors said Kansas City police got a call the next day from Salazar, offering information about the case.

In numerous interviews with police and the FBI, Salazar said three men he saw at a friend’s apartment talked about trying to rob the bank.

FBI agent Michael G. Mrachek said in the affidavit that Salazar was focused on the reward.

“Salazar’s motivation for cooperating … was financial in nature,” Mrachek said.

As discrepancies and inconsistencies crept into Salazar’s story, authorities questioned him at police headquarters again on Tuesday, this time reading him his Miranda rights. They had come to the conclusion that Salazar himself had been in on the plot.
