On January 4, 1982, the body of Phyllis Ellen Tamm, 27, was found hanging from a small tree in an affluent neighborhood near Rice University in Houston, Texas. She was dressed in jogging clothes and was sitting just inches off the ground; the only visible marks were from knitted fabric wrapped around her neck. Authorities initially could not determine whether her death was suicide, accident, or homicide, and the medical examiner could not conclusively determine the cause.

Tamm worked at an advertising company and had no known history of mental illness or suicidal behavior. In August 1982 Coral Eugene Watts confessed to attacking her while she was jogging, saying he choked her with his hands and then hung her from a tree branch with an elastic strap. Watts was arrested in May 1982; in a plea deal he was granted immunity from prosecution for several murders, including Tamm’s, in exchange for confessions and cooperation locating burial sites, so no charges were filed specifically for her death.

Does anyone have memories or information about Phyllis, her work, or her routine in Houston in early 1982?
