OLMOS PARK, Texas — Police have arrested someone else as the search continues near San Antonio for a missing Texas mother.

It’s been more than two weeks since Texas mother of four Suzanne Simpson was reported missing from Olmos Park, Texas.

Today, police arrested her husband’s former business associate, Brad Simpson.

James Cotter is accused of helping Brad Simpson hide a gun possibly linked to his wife’s disappearance.

A neighbor reportedly witnessed an altercation between the Simpsons before Suzanne disappeared.

Brad Simpson is currently behind bars for this incident, charged with assault and unlawful restraint.

“This whole thing is just a strategy regarding a homicide investigation or what they think is a homicide investigation. And so, they’re using this to keep him in jail for 30 days,” said Robert Boyce, former NYPD Chief of Detectives.

Police say Brad Simpson was uncooperative.

Investigators expanded their search for Suzanne Simpson to a dump last week, but found no sign of her.

Cotter faces criminal charges including “tampering with evidence.”

As for Simpson, his lawyer calls the accusations against him “ridiculous.”
