HOWELL, Mich. (AP) — A Michigan man who drew scrutiny from investigators after a Facebook post about how to spend $30,000 has been sentenced to life in prison in the slaying of a landscaper known to carry cash.

WHMI-FM and the Livingston Daily Press & Argus of Howell report Monday that Anthony Sean Duke told a Livingston County court that he was innocent in the fatal shooting of 47-year-old Ronald Hauser.

The 26-year-old Duke of Webberville was convicted of murder. Hauser was found slain in December 2011.

A sheriff’s investigator has said he repeatedly questioned Duke after learning about the 2012 social media post.

Authorities say the post read: “What to do?? … 30K I have to spend.”

The post was made about a month after Hauser’s death.

Duke was charged in 2014.
