BCSO deputy arrested, accused of injuring estranged common-law wife with knife

Andrew McDermott, 26, charged with aggravated assault with deadly weapon

SAN ANTONIO – A Bexar County sheriff's deputy was arrested early Wednesday in connection with a domestic violence incident involving his estranged common-law wife.

Andrew McDermott, 26, had returned from a trip from out of state and asked his estranged wife if he could sleep at a home they once shared in the 13300 block of Nueces Parke, Bexar County Sheriff Javier Salazar said.

The 37-year-old woman allowed McDermott to sleep on a sofa, and at some point during the night, the two got into a confrontation over text messages the woman had received, Salazar said.

McDermott tried to take a cellphone from the woman's pajamas and when he pulled out a pocketknife, she got cut in the arm, Salazar said. The woman was treated at the scene by EMS.

The suspect fled the scene and was arrested by a deputy who recognized his vehicle.

McDermott is charged with aggravated assault with a deadly weapon and has been ordered by a judge to stay away from his wife for 90 days, Salazar said.

The sheriff said that McDermott was already in trouble with the law enforcement agency over several cases of incidents involving force with inmates at the Bexar County Jail. He was placed on administrative leave in April while the cases are investigated.

Salazar said he would like to "separate (McDermott) from BCSO as soon as we can."

McDermott was charged in another family violence case in 2016, but the case was dismissed, Salazar said.

McDermott and his wife are in the process of getting separated and their home is in eviction proceedings, Salazar said.

The couple have two children.
