Teenage Floridian William Aydelott was arrested last night after his mother was found dead, with a knife sticking out of her eye. The Northwest Florida Daily News says he fessed up to the killing, "calm and emotionless," as soon as police took him in.

The Daily News says Aydelott and his mother had been butting heads for months, but there's no indication of why they went from arguing to the teen beating his mother with a baseball bat, slashing her throat, and sticking the knife in her eye.

"This is a sad day for that family," said Tim Wyrosdick, superintendent of Santa Rosa County schools.

Aydelott remains in custody with no bond set.
