MONTROSE, Pa. (AP) - A jury has found a northwestern Pennsylvania woman guilty in the death of a man who was stabbed 29 times before his body was dumped down an embankment along the Susquehanna River.
The jury deliberated about four hours Wednesday before returning the verdict against 28-year-old Sarah Briggs in the Feb. 2015 death of Roy Marvin.
Her boyfriend, 26-year-old Jerry Mast, pleaded guilty in December in the stabbing, which police say was over an argument about drugs.
On Tuesday, Mast testified that he stabbed Marvin with a folding pocket knife and Briggs then used a kitchen knife to stab Marvin in the chest.
On Wednesday, she told the jury her boyfriend stabbed Marvin. She also described her descent into heroin addiction.
She says she felt guilt about Marvin’s death because her actions led up to it.
