Two Houston men have entered guilty pleas in connection with a violent bank robbery in Humble.
Justin Devon Hayes, 23, and Demontray Ward, 21, both plead guilty to aggravated robbery with a deadly weapon.
Investigators said back on April 26, Hayes, Ward and a third man who's now dead, robbed the Regions Bank in the 7000 block of East FM 1960 in Humble.
Ward was armed with a shotgun, while the other two had pistols.
According to authorities, the men demanded money, threatened the tellers and became upset when they realized the vault was on a 10-minute timer.
A Houston police officer entered the bank, but was disarmed by Ward.
Outside, another officer witnessed the three men leave the bank in an SUV. He attempted to confront them, but the vehicle drove towards him.
Seeing a shotgun pointed at him, the officer fired and the driver was shot and killed.
Ward and Hayes were then taken into custody.
A U.S. District Judge has set sentencing for spring 2014.
Both men face up to 25 years for the bank robbery as well as a consecutive seven years for the firearms charge. They will remain in custody.
