WASHINGTON (WUSA9) -- Two cousins were sentenced to prison on Wednesday for a series of armed robberies they were involved in Northwest and Northeast D.C. on Christmas Eve and Christmas of 2012, officials announced.

Floyd Long, 23, of D.C. was sentenced to 19 and a half years in prison and his cousin Alonzo Ferrell, 23, of Capitol Heights, was sentenced to 15 years in prison for the robberies they were involved in, said U.S. Attorney Ronald C. Machen Jr.

The cousins were found guilty by a jury in November 2014 of conspiracy, armed robbery, receiving stolen property, fleeing law enforcement, and other weapon offenses, according to officials.

After completion of their prison terms they will both be placed on five years of supervised release.

The two men along with two accomplices got four handguns and a stolen car and then conspired to commit armed robberies in D.C. on Christmas Eve. The four men drove around residential areas looking for potential victims.

They robbed their first victim at gunpoint around 11:15 p.m. in the 200 block of Hamilton Street NW. They stolen his iPhone and an iPad, authorities said.

The four men then drove to the unit block of Webster Street NE, and robbed their second victim at gunpoint. They stole a cellphone and $160. They then drove to the 600 block of Jefferson Street, NE and pointed a gun to the victim's head while he was bringing gifts into his home. They stole $3 and a cell phone.

On Christmas Day at 12:12 a.m. the men assaulted a victim in the 1700 block of Varnum Street NE. They stole his wallet with $15 inside.

The four men were spotted in the stolen car in the 5600 block of Central Avenue SE. After a brief chase Long and Ferrell were taken into custody.
