Batavia, Ohio (AHN)-An Ohio man, who neighbors say was extremely devoted to his meticulously kept lawn, has been charged with murder in the shooting of a 15-year-old boy who apparently walked across his yard.

According to nbc4.com, a 911 tape recorded 66-year-old Charles Martin saying, "I just killed a kid." Martin also told a dispatcher, "I've been harassed by him and his parents for five years. Today just blew it up."

According to police, Martin and teenage neighbor Larry Mugrage had a history of arguments about Martin's yard. Police say the two argued again Sunday, but this time when Mugrage returned, Martin was waiting outside and shot him twice.

Neighbors say Martin lived alone quietly, often sitting in front of his one-story home with its neat lawn, well-trimmed shrubbery and flagpole with U.S. and Navy flags displayed. Authorities say Martin has no prior criminal record, but he does have a history of complaints about neighbors allegedly damaging his property.

Described by neighbors as "a good kid," Mugrage, a student at Glen Este High School, was pronounced dead at a local hospital.
