A St. Clair area man is facing a manslaughter charge in the death of his girlfriend’s son early Friday.

Prosecuting Attorney Bob Parks issued a felony complaint shortly before noon Friday charging Richard A. Sears, 41, 1132 Highway TT, with involuntary manslaughter. Parks requested a $50,000 cash-only bond in the case.

Sheriff Gary Toelke said the 41-year-old suspect came home intoxicated about 2 a.m. Friday, June 8, and got into an argument with his long-term girlfriend.

The victim, 18-year-old Matthew Indelicato, intervened and was struck during a physical confrontation, the sheriff said.

The teen then suffered an extreme asthma attack and stopped breathing, according to the sheriff’s report.
