Knoxville (WVLT) - Knox County Sheriff Tim Hutchison says a man who allegedly tried to rob Knox County Commissioner Greg Lambert is a suspect in the murder of a Walgreens truck driver.

Sheriff Hutchison made the announcement today at the commission meeting.

Hutchison says he will ask a grand jury to indict 19-year-old Kane Stackhouse on murder charges Tuesday.

So far Stackhouse has not been charged with anything in connection with the murder of 53-year-old David Lindsey behind the Walgreens in Powell early in the morning on November 11th.

Stackhouse had not even been named a suspect until Monday.

But Stackhouse is charged with attempted robbery for allegedly pulling a gun on Commissioner Lambert about ten hours after Lindsey was found dead.

Deputies say Lambert foiled the alleged robbery by pulling a gun on Stackhouse.
