The husband of a woman found dead inside their Staten Island home last summer was charged yesterday with her murder, cops said yesterday.

Both suspect Jonathan Crupi, 30, and victim Simeonette Mapes-Crupi, 29, were teachers at the same Brooklyn high school.

He was collared at his mother’s Brooklyn home, where he had been staying since the July 5 slaying.

“I was shocked when police called this morning — because they said it was my son-in-law,” said the victim’s mom, Theresa Mapes. “I really didn’t want it to be him.

“They were madly in love, but toward the end, they had a few arguments,” she added.

“We started to suspect him a few weeks later because he just stopped calling us.”

Mapes-Crupi was found with 15 stab wounds in the couple’s ransacked condo.

“The allegations are unfounded,” said Crupi’s lawyer, Mario Gallucci.
