Authorities say a central Pennsylvania father shot and killed his 2-year-old son and wounded his estranged wife before killing himself.

Huntingdon County District Attorney George Zanic says 52-year-old Kenneth Ayers had gone to his mother’s home near Petersburg on Saturday to exchange custody with his estranged wife.

Authorities said an argument broke out and he shot the woman in the legs, right arm and face and killed their son, Michael. Zanic says the woman had obtained a protection from abuse order against her husband.

Kenneth Ayers’ body was found several hours later in his truck in a wooded area nearby in Warriors Mark Township. Police said he died of a self-inflicted gunshot wound.

Petersburg is about 20 miles southwest of State College.
