An Indiana man who stopped taking medication for paranoid schizophrenia stabbed his mother 21 times over his non-existent inheritance, police said.

Vinson Edge, 39, of Speedway, was arrested Monday in connection with the slaying of his mother, 58-year-old Vickie Edge, the night before.

She was stabbed with two kitchen knives in her head, neck, hands, arms and chest after an argument with her son over money, the Indianapolis Star reports.

Cops found the man’s brother outside of the family’s apartment complex holding a bat as he told investigators that Edge had killed their mother, whose body was found inside near a large kitchen knife, court documents show.

Edge had stopped taking his medication for paranoid schizophrenia about a month earlier, his brother told cops, prompting him to act erratically. Edge was not known to be a violent person prior to the change, his brother said.

Edge, who fled the apartment, was busted the following day after police got a tip that he was going to meet up with his mother’s longtime boyfriend, WXIN reports.

Terry Brown, 52, shot Edge in the leg just before he was taken into custody. A witness told the station that Brown and two others subdued Edge as they waited for cops to arrive.

Brown is now facing a charge of battery with a deadly weapon and is expected to appear in court on Thursday, the Indianapolis Star reports.

Relatives, meanwhile, said they saw no signs of trouble prior to the fatal stabbing that took away the “heartbeat” of the family, according to Samantha Riley, who is married to Vickie Edge’s nephew.

“It was no means, merit, there was no argument,” Riley told WXIN. “It just happened out of the blue.”
