A Florida high school football coach was fatally shot at his home — and his 15-year-old nephew is a suspect in the slaying, according to a report.

Miami Senior High School football coach Corey Smith, 46, died at his home in northwest Miami-Dade County from “multiple gunshot wounds” early Monday, and his teen nephew — who has yet to be identified — was the only other person known to be inside the residence at the time, the Miami Herald reports.

The teen, who was speaking with detectives Monday, had been staying with Smith following the death of his father — Smith’s brother — in December after he and another man hijacked a UPS truck and died in an ensuing shootout with police, the newspaper reports.

“The 15-year-old in the home was unharmed,” Miami-Dade Detective Alvaro Zabaleta told the Herald. “We’re still waiting on a warrant to get into the home.”

Smith’s nephew said he was studying inside the home when he heard gunshots, law enforcement sources told the newspaper.

Neighbor Willie Jones said Smith was known to get his players “on the right path,” including into college and beyond.

“There’s a lot of kids that’s in the league, college, probably wouldn’t have made it through high school without him because he was always there for them like a big brother, uncle, father figure,” Jones told WPLG.

Smith also taught at Charles Drew Middle School in Miami-Dade’s Brownsville section, where he helped form the future NFL career of T.Y. Hilton, who now plays wide receiver for the Indianapolis Colts, his father told the station.

“He touched a lot of lives, a lot of young minds,” Hilton’s father, Tyrone, told the station. “A role model in this community.”

University of Miami football coach Manny Diaz told reporters at a press conference Monday that he and his staff were “deeply saddened” by Smith’s death, which came less than 24 hours after the father of New England Patriots running back James White — a former star at St. Thomas Aquinas High School in Fort Lauderdale — died in a car crash in Broward County.

Tyrone White’s wife and James White’s mother, Lisa, who was driving, remained in critical condition Monday, the Herald reports.

“It’s been a very difficult year in the South Florida high school coaching community,” Diaz said. “This is another difficult moment. It was hard news to hear that this morning.”
