WYALUSING, PA. (WENY) – The man convicted of killing his mother and dumping her body in the Wyalusing Creek last year was sentenced to prison Friday.

According to the Bradford County District Attorney's office, 39-year-old Matthew Haverly of Camptown was sentenced on charges of involuntary manslaughter, abuse of a corpse, tampering with evidence and possession of a weapon. He has been sentenced to the Pennsylvania State Correctional Facility for three and a half to 14 years, plus additional fines and court costs.

Haverly has reportedly been in the Bradford County Correctional Facility since his arrest on June 1.

As WENY News reported, Haverly was arrested after 60-year-old Patricia Haverly was found dead in the Wyalusing Creek on May 31, 2018.

Haverly reportedly told police he and his mother had a “tumultuous relationship” and before Patricia's death, they had gotten into an argument.

According to The Star Gazette, Matthew said he and his mother then got into a physical fight in which his mother tried to punch him in the face. According to Matthew, he grabbed her by the arms and pushed her away, and then “blacked out at that point and couldn't remember anything that happened afterward”.
