Abby Hill was 31 and from Alpena, Michigan. She was killed on September 25, 2021, after becoming entangled in the disappearance and murder of 17-year-old Brynn Bills earlier that summer.

In September 2021 Hill had been arrested on an unrelated warrant and questioned, then released. Investigators say Srebnik and Wirgau feared Hill might reveal the burial site, and on September 25 the three went to a remote wooded area in Alpena Township. There, Srebnik allegedly shot Hill once in the back of the head and left her body at the scene; her remains were recovered on October 15, 2021.

Does anyone have information about Hill’s movements in Alpena Township in September 2021 or knowledge of the remote camping area where she was found?
