Authorities allege Beth Beamer had not adequately cared for the victim for four years. According to the report, she admitted to dumping the woman’s body at an out-of-state location and collecting her social security benefits. 

Meanwhile, the sheriff’s office has fired one of its deputies after discovering he failed to adequately handle the Beamer case and acted in a manner "unbecoming of a deputy," according to the report. Additional details regarding the deputy’s dismissal were not immediately available.
