Janice Marie Dickinson, 33, was found dead on June 19, 1986, on a grassy hillside behind a car dealership on Coburg Road in Eugene, Oregon. Her naked body showed she had been sexually assaulted, stabbed, strangled, and beaten. She had last been seen walking near Alton Baker Park.

Her murder was linked to two other brutal slayings in the area, those of Gladys May Hensley and Geraldine Spencer Toohey, because of similarities in the crimes. The case remained unsolved for decades despite investigators pursuing multiple leads and persons of interest.

Advances in forensic technology produced renewed progress: Snapshot Phenotyping was used in 2016, and genetic genealogy work in 2018 pointed to John Charles Bolsinger, a man with a prior murder conviction who had been paroled to Springfield, Oregon, months before Dickinson’s killing. Bolsinger died by suicide in Springfield on March 23, 1988, before he could be prosecuted.

If anyone knew Janice, saw her near Alton Baker Park on June 19, 1986, or has information about these cases, please come forward.
