Convicted murderer Anthony Paul White Jr. was back in court Tuesday, this time pleading guilty for his role in several robberies.

White, 22, was sentenced to a total of seven to 14 years in state prison, to run concurrently with his life sentence for second-degree murder. At the time of his crimes, White was living with a family member on South Penn Street in York City; he previously lived in Baltimore.

White fatally shot Christopher Armagost, 30, at the victim's 315 S. Penn St. home on Dec. 10, 2011, during a botched robbery.

White was free on bail pending sentencing on a convenience-store robbery when he murdered Armagost.

The gun he used to kill Armagost was used a month before that to murder 44-year-old crack-cocaine dealer Stanley Cotton. Police said Cotton was lured inside 612 W. Market St. on Nov. 10, 2011, and killed during a robbery.

Robert C. Williams, 36, was convicted of second-degree murder and robbery and sentenced to life in prison for luring Cotton to the apartment building. The man who actually shot Cotton remains at large, although prosecutors said the case is still being actively investigated.

Williams' father and uncle were married to sisters of White's grandmother, according to York City detectives.

Guilty pleas: On Tuesday morning, White pleaded guilty to robbery and conspiracy to commit robbery for carjacking a man at gunpoint in York City on Nov. 28, 2011; robbing Turkey Hill Minit Market on Carlisle Road in Dover Township at gunpoint on the same date; and robbing a pizza-delivery driver at gunpoint in York City on Dec. 11, 2011, according to senior deputy prosecutor Seth Bortner.

He also pleaded guilty to receiving stolen property after police found a robbery victim's belongings in White's bedroom. That robbery happened on Jan. 4, 2010, officials said, and the victim's wallet was recovered by police on Dec. 11, 2011.

Defense attorney Joshua Neiderhiser said White pleaded guilty to the robberies "to wrap up these cases."

While entering his pleas, White blamed the gun-wielding aspects of the crime on co-defendant Ronald D. Sweeney Jr.

Violent ring: York City detectives have said White and Sweeney were part of a violent robbery ring that targeted numerous individuals and businesses.

In June, a federal grand jury indicted Sweeney for allegedly carjacking a York City grandfather who was left paralyzed by a gunshot.

Police said Sweeney shot Raymond Hernandez in the back about 2:40 p.m. Oct. 5, 2011, as the victim waited outside Lincoln Charter School to pick up his grandson.

Sweeney, 21, is also accused of robbing a 75-year-old man in broad daylight; robbing a pizza delivery person at gunpoint; and robbing a York City corner store at gunpoint.

Sweeney pleaded guilty Monday in federal court to carjacking Hernandez. A sentencing date has not yet been set. His York County cases are still pending; he has pretrial conferences set for March 19.
