Authorities say a convicted felon who was a suspect in the kidnapping and killing of a Swedish exchange student who disappeared in the San Francisco Bay Area in 1982 has been long dead.

The Marin Independent Journal reports (http://bayareane.ws/1G6Rlk8 ) that a Social Security Administration spokeswoman says Henry Lee Coleman died Feb. 5, 1988. There was no record on where Coleman died or a cause of death.

The U.S. Department of Justice matched seven bones discovered in a Fremont canyon five years ago to Elisabeth Martinsson. She was living with a family in Marin and was out shopping with their borrowed car when she disappeared.

Martinsson's identity was released publicly last month.

Shortly after she disappeared, Coleman was arrested on auto theft while authorities investigated the Martinsson case as a potential homicide. Coleman eventually was convicted of auto theft and went to prison.
