A Border Patrol agent accused of fatally shooting a 27-year-old man following an argument last month pleaded not guilty Wednesday, CBSLA.com reports.
John Richard Demery, 40, is charged in the killing of Adam Thomas in an early morning dispute.
Demery was off-duty at the time.
Prosecutors said the confrontation may have been prompted by a speeding or racing incident.
Demery is in jail on a $1 million bond.
