A Texas Air Force major was arrested for tampering with evidence in connection with the disappearance of his wife, who was reported missing Friday after she failed to show up to the assisted living facility she owned.

KENS reported that Bexar County police executed a search warrant at the couple’s home and recovered a recently-purchased ax, work gloves, and gasoline. Authorities believe missing woman Andreen McDonald’s husband, Andre McDonald, 40, bought the items to dispose of her body but suspect he didn’t have the chance to do so.

The San Antonio Express-News reported that Andre was charged with tampering evidence after officers recovered a torn-up receipt for the purchase of those items.

Bexar County sheriff Javier Salazar said Andreen is presumed dead and that investigators are using cadaver dogs to search ravines and creeks.

Andre and Andreen, 29, share a 6-year-old daughter who is non-verbal with autism, and who authorities believe possibly witnessed something happening to her mother. Salazar said Andre works in cyber warfare at the Lackland Air Force Base and that his mental health isn’t in question.

While Salazar indicated that it’s possible Andreen fled the country, authorities suspect foul play is involved in her disappearance as she left behind items that wouldn’t be abandoned when leaving the country. They also noted that Andre hasn’t been cooperative in their investigation.

Moreover, court documents obtained by the Express-News stated that two concerned friends of Andreen found a burn pile in the back of the McDonalds’ home and blood and hair on a light switch located inside the couple’s master bedroom. A search of the home Saturday reportedly uncovered human blood in the bathroom.

Authorities said the pair gained access to the home through an unlocked door after Andreen didn’t report to work. Police said they were the ones to report her disappearance Friday afternoon.

“The first witness said that the Missing Person (Andreen McDonald) told her many times if she ever went missing it would be because the Suspect killed her,” the affidavit stated.

Records obtained by the newspaper revealed that Andre had filed for divorce in 2017 but later had the case dismissed. He remains jailed on $2 million bail.
