A Houston man is charged with stalking after San Antonio police said he harassed an insurance claims adjuster and slashed her car tires, according to an arrest affidavit.

Jeffrey Maddox, 37, was charged in the incident after a USAA insurance claims adjuster filed a complaint with SAPD.

According to an arrest affidavit, Maddox’s wife was involved in a car accident and the other driver involved was insured through USAA. Maddox emailed the adjuster multiple times about the claim, which led to USAA transferring the claim due to his emails becoming more threatening, police said.

On Nov. 3, the woman emailed Maddox, telling him to no longer email her due to his ‘verbal abuse on the phone and hostility through email correspondence,’ an affidavit states.

Maddox was able to find the woman on social media and police said he continued to email personal information about her that he had found. On Nov. 12, the woman had four of her tires from two different cars slashed by a sharp object.
