LINESVILLE — The state departments of Environmental Protection and Health, and the Fish and Boat Commission issued a "do not eat" advisory for fish caught at Pymatuning State Park in northwestern Pennsylvania.

The warning was issued Thursday because the agencies said about 2,500 fish have died without explanation in the park's reservoir since May 15.

Park officials said it doesn't appear the fish kill is affecting the carp that have made the park's Linesville Spillway a tourist attraction. The carp throng so thickly for bread tossed by visitors that ducks can walk on the fish.

Instead, hundreds of crappie, muskie, walleye and bass have died in other parts of the reservoir. Biologists are studying the dead fish for clues.

PITTSBURGH — A thief turned out to be no match for a little nun with a commanding voice.Sister Lynn Rettinger didn't even have to break out a ruler for a man who reached into an opened car window and stole a wallet Tuesday. She just needed the tone of voice she's used for nearly 50 years in Catholic schools.After a teacher saw the man swipe the wallet, the 5-foot-3 principal of Sacred Heart Elementary School went outside and firmly told the man: "You need to give me what you have." The thief turned over the wallet, apologized and walked away.Rettinger said she merely talked to him as she would to students when she knows they have something they shouldn't.Police are still looking for the man.

LANCASTER — A couple thousand people in Lancaster lost power, and two schools had to open late — thanks to a squirrel.Officials said the power outage affected about 2,700 Lancaster city residents about 6:30 a.m. Thursday. Two elementary schools also delayed the start of classes for two hours because they had no electricity.PPL spokesman John Levitski said there was a tree down in the same area but the culprit in the power outage was much smaller: a squirrel that chewed on overhead power lines.
