Olmos Park realtor Suzanne Clark Simpson's husband has been charged with murder following her disappearance

Bexar County officials charged 53-year-old Brad Simpson with murder Thursday, a month after his wife, Olmos Park real estate agent and mother of four Suzanne Clark Simpson, disappeared.

He also faces four other charges, including assault, family violence, unlawful oppression, tampering with or fabricating physical evidence with intent to impair, and a prohibited weapons charge, a Bexar County Records clerk said Thursday.

His long-time business partner, 65-year-old James Cotter, was arrested on two offenses including tampering with evidence with intent to impair an investigation and possession of prohibited weapons.
