(Radio Iowa) – Police say a long-running fight over a lawn tractor led to the shooting death of a Des Moines woman. On Sunday night, a 9-1-1 caller expressed concern about a woman and police found 42-year-old Amber Burton of Des Moines dead of what was originally thought to be a stab wound.

An autopsy determined she died of a gunshot wound. Fifty-year-old Des Moines resident Nery Arnoldo Lopez Morales has been charged with the woman’s murder. Police say Morales and Burton had an ongoing dispute about the ownership of a lawn tractor and witnesses and surveillance video connected him to her death.
