WARFORDSBURG, Pa. (AP) - A man who authorities say left more than 800 pigs to die at a farm he abandoned in southcentral Pennsylvania has been charged with animal cruelty.

State police filed a criminal complaint Thursday against 47-year-old Daniel Lee Clark Sr.

The pigs were discovered last month by a real estate agent inspecting the property in Warfordsburg. Estimates have varied on the number of animals; police now say 832 died.

Lt. Greg Bacher (BATCH'-er) tells The Philadelphia Inquirer that the mummified carcasses make it hard to know the cause of death. Weather, thirst or disease could have been factors.

Authorities say Clark abandoned the Fulton County farm in February 2009. Clark now lives in Clear Spring, Md., but a phone listing could not be found.
