LOCK HAVEN, Pa. — A man who reported his wife missing in central Pennsylvania, prompting a weeklong search, but was later charged in her murder has been sentenced to 20 to 42 years in prison.

William Snyder, 36, of Renovo, pleaded guilty in Clinton County in December to third-degree murder, false reports, abuse of a corpse and evidence tampering in the death of 34-year-old Kelley Jo Snyder.

Authorities said he strangled his wife on Easter Sunday 2015 and dumped her body next to a stream in Halls Run State Park. Officials said he tried to cover up the crime by reporting her missing, preparing a $60,000 ransom note and going on television to plead for her safe return.

Snyder apologized in court Friday to his wife’s family and those who searched for her, saying “I never meant for this to happen,” and for the first time gave his version of events.

He said he and his wife got into an argument that turned physical, ending with him straddling her and his hands around her neck, and several minutes later he realized she wasn’t breathing. He said he tried to cover up his actions because “I did not know what to do.”

“I should have instantly called 911. To this day I don’t know why I didn’t. One lie turned into another lie I didn’t know how to get out.”

Snyder also said depression and post-traumatic stress disorder contributed to his actions, but the judge was having none of it.

“We are here today because you cannot control your anger,” Judge Michael Salisbury said. “It’s as simple as that.”
