MADISON, Wis. -

Two men were sentenced to prison for the May 2012 armed robbery of Heller's Recycling in Madison, according the U.S. Attorney's Office.

Donnie L. Taylor-Young, 21, of Madison, and Traveon Spencer, 25, of Chicago, both pleaded guilty to the robbery charges in February and were sentenced Tuesday.

Taylor-Young was sentenced to seven and a half years in prison and Spencer was sentenced to eight and a half years in prison.

A federal grand jury indictment also charged Taylor-Young with brandishing firearms -- namely shotguns -- during a crime of violence.

Prosecutors said the robbery was captured by a video camera. Video showed Spencer entering the business with a shotgun and ordering employees to the ground while pointing a shotgun at them. Another camera showed Taylor-Young and another person entered the office wearing masks, according to prosecutors. He was unarmed and took $81.

DNA from a shirt that fell off of Spencer's head was connected to him and Spencer admitted to robbing the recycling center, according to police. Taylor-Young also confessed when approached by police.
