Hours after Casey Anthony learned on Thursday that she will leave jail next week, lightning apparently struck a tree next to a makeshift memorial in honor of her slain daughter, Caylee.

No one saw lightning strike the pine tree on Suburban Drive in Orange County, Florida, where teddy bears and flowers mark the spot where 2-year-old Caylee's remains were found on December 11, 2008.

But long, diagonal strips of exposed wood scarred the tall pine tree, WESH reported, and bits of bark lay scattered across the road.

"It could be a sign from the angels that they aren't happy with what's happened," a visitor to the site told the Orlando Sentinel newspaper. "The rain, the lightning, the storm - it's the heavens indicating they aren't happy."

There are more lightning strikes in Florida per square mile than in any other state, according to weather.com.

A Pinellas County jury acquitted Anthony, 24, of murder and manslaughter charges Tuesday in the death of her daughter. The same jury convicted her of four charges of obstruction of justice for lying to police during the search for Caylee.

Judge Belvin Perry sentenced Anthony to four years in jail - one year for each of her four convictions - but with credit for nearly three years already served and good behavior, her release date was set for Wednesday, July 13, a court spokeswoman said.
