CHESTNUTHILL TOWNSHIP---State police said 19-year-old David Crothers is dead.
Investigators said he was stabbed in the leg last week at his home on Locust Lane in Chestnuthill Township, Monroe County.
Crothers died over the weekend at Pocono Medical Center.
His mother told Newswatch 16 Crothers was fighting with his younger brother, 18-year-old Matthew Crothers at the family's home.
She said the argument was about David Crother's girlfriend.
At one point, Gabby Crothers said Matthew stabbed David in the leg, a decision she calls 'tragic' and 'horrible.'
She said Matthew did not mean it and if charged with homicide, she added she will get him an attorney and help in any way she can.
Officials at the Monroe County prison said Matthew Crothers is currently locked up, arrested and held since the day of the stabbing on a county parole violation.
He has not been charged with homicide, nor has anyone else.
State police said the investigation is ongoing.
