A Gainesville man accused of vehicular homicide in the fatal crash with a Lula councilwoman has been ruled mentally incompetent to stand trial, according to documents.

Joshua Wiley Armour was indicted in February 2015 on charges of first-degree vehicular homicide, serious injury by vehicle, misdemeanor driving under the influence, reckless driving, no insurance, failure to maintain lane, driving on the wrong side of the road, having an open container and a seat belt violation.

On Jan. 10, 2015, authorities said Armour struck Vicky Chambers’ car head-on.

Chambers, a Lula councilwoman, died Jan. 22, 2015, after suffering critical injuries, and her passenger Lisa Page also received injuries.

Armour’s attorney Brett Willis declined to comment.

Two doctors, Dr. Justin Donaldson and Dr. Robert Shaffer, offered their opinions on Armour’s rare diagnosed condition, which causes cognitive “deterioration and impairment,” according to an April 26 order.

One doctor said Armour exhibited “very severe” short-term memory problems and would have difficulty making decisions.

“Having carefully considered the written and oral testimony provided by both Dr. Donaldson and Dr. Shaffer, the Court finds it difficult to believe that Mr. Armour’s present impairments would not significantly hinder his ability to assist in his defense,” according to Superior Court Judge Kathlene Gosselin’s court order.

Armour will be be transferred to the Department of Behavioral Health and Developmental Disabilities’s custody, where he will be evaluated to see if he could stand trial in the future.
