Man convicted of killing researcher Pitcairn sentenced

A man convicted of fatally stabbing a Johns Hopkins researcher during a robbery has been sentenced to life in prison plus 20 years.

Thirty-eight-year-old John Alexander Wagner was sentenced on Friday. He had been convicted in August of first-degree murder and armed robbery in the stabbing death of 23-year-old Stephen Pitcairn.

Pitcairn was robbed and stabbed in July 2010 while talking on a cell phone with his mother. He had been walking home from Penn Station.
