Update: Barry Domingue has died after shooting himself, according to our news partners at KATC.

U.S. District Judge Elizabeth Foote declared a mistrial in a synthetic marijuana case, hours after one of the defendants shot himself.

The Advocate reports Barry Domingue, a lawyer from Carencro, is being treated at Lafayette General Medical Center for a gunshot wound to the head.

U.S. Attorney Stephanie Finley said Domingue left a suicide note that could contain information germane to the case.

Domingue and Lafayette lawyer Daniel Stanford were standing trial on various conspiracy charges.

After Wednesday's turn of events, Stanford requested a mistrial, which Foote granted.

Domingue and Stanford were on trial for their alleged roles in running a string of Curious Goods stores, which prosecutors have said sold illegal synthetic marijuana branded as Mr. Miyagi.
