Former Gophers linebacker Gary Tinsley died naturally of cardiomegaly — more commonly known as an enlarged heart — the Hennepin County Medical Examiner announced Wednesday.

Tinsley was found unresponsive in his room at Roy Wilkins Hall on April 6 by his teammate and roommate Keanon Cooper, and paramedics were unable to revive him.

Tinsley was a four-year member of the Gophers football team and started every game in his final two seasons with the Gophers. He led the team with 90 tackles as a junior and had 87 tackles and four sacks his senior season.

Tinsley’s funeral was held April 14 at Abyssinia Missionary Baptist Church in his hometown of Jacksonville, Fla. The Florida Times-Union reported that an estimated 1,800 people gathered at the funeral to honor Tinsley, who was 22.
