SPRINGFIELD, Mo. (AP) — A man who was injured in a fight with a neighbor on Labor Day has died from his injuries.

Greene County authorities said Thursday that charges were upgraded against the man suspected in the death of 55-year-old Edwin Carey.

Carey was found unresponsive in the front yard of a home in Springfield on Sept. 4. He died Tuesday.

Prosecutors say 41-year-old Jimmy Davis, who was originally charged with assault, is now charged with involuntary manslaughter.

Online court records do not name an attorney for Davis.
