PLEASANTON -- The wife of a former police commander suspected of conspiring with her husband to defraud an elderly Pleasanton woman has surrendered to authorities, police said Tuesday.

Elizabeth Regalado, 30, turned herself in at Hayward police headquarters on Friday, Pleasanton police Sgt. Kurt Schlehuber said. She was charged with one count of felony conspiracy to defraud her 82-year-old neighbor, Schlehuber said.

Regalado's husband, former Pinole police Cmdr. Matthew Messier, 36, was arrested at his Pleasanton home Friday and has been charged with several crimes, including four counts of elder abuse and three counts of attempted grand theft. Regalado posted the $20,000 bail and is free from custody, pending her next court appearance, the date of which was not available immediately.

Jail records indicate Messier also posted his $322,500 bail.

According to police, Messier and Regalado convinced the victim to put her entire estate into a trust fund that he and Regalado controlled. The assets were estimated by police to be between $750,000 and $1 million.
