Authorities are investigating the shooting death of a Waterloo woman over the weekend.

60-year-old Ronald Rand is accused in the Sunday shooting which killed his girlfriend, 51-year-old Michelle Key, at a house in Hampton.

A release from the Hampton Police Department said dispatchers received a call just before 6 p.m. reporting a possible suicidal person at a home in the 600 block of First Street NE. Arriving officers found Key's body and said she had died of a gunshot wound.

Officers arrested Rand on a charge of first-degree murder. Rand is being held in Franklin County custody awaiting his initial court appearance and could not be reached for comment. Online court records do not yet list an attorney.
