On the morning of September 8, 2017, Lisa Marie Willson, 51, was found dead in her Williamston, Michigan, home from a single gunshot wound to the back of her head while she slept. She was a Financial Technical Advisor and mother of two sons, Michael and Andrew.

The initial call to police came from her younger son, 19-year-old Andrew Willson, who said he found his mother dead after returning home. Investigators noted inconsistencies in his account, took him into custody as the primary suspect, and say he later confessed. According to the statement attributed to him, after an argument about a puppy his mother would not allow him to keep, he retrieved a .22 Magnum rifle from a locked cabinet, entered her bedroom while she slept, and shot her. He was charged with murder and felony firearm possession and held without bond.

Andrew’s defense raised issues of major depressive episode and hearing voices at the time of the killing; family members urged a treatment-focused sentence. For readers who knew Lisa or have information about the case, is there anything not yet reported that could help clarify what happened?
