Lisa Bollaert was 37 when she arrived in Tulsa in spring 2009 after hitchhiking from her home in New York. A former U.S. Army member and a mother, she had recently left a treatment facility and stayed at a Salvation Army shelter and then a women's shelter in late April and early May while trying to start over.

On May 6, 2009, a homeowner found a garbage bag on their front yard containing Bollaert’s body. Her arms and legs were bound with duct tape, and her body showed severe beatings and lacerations. Authorities described her death as the result of extreme rage. Surveillance from the days before her death shows Bollaert outside the Tulsa FBI office in the company of an unidentified white man estimated to be in his 40s or 50s; he was sought for questioning but was never publicly identified. DNA was collected at the scene, but no suspects have been publicly named and no arrests have been announced.

Does anyone have information about Bollaert’s movements in Tulsa in late April or early May 2009, or recognize the man seen with her on surveillance?
