Carlos Alvarado, 45, is charged with murder in the death of his wife, Isabel. She had been missing for a week and then her burned remains were found in Fort Bend County on property owned by Alvarado's aunt. He told family members he was burning an animal.
Prosecutors say Alvarado confessed to choking his wife because he found her with another man. He was initially being held on $100,000 bail, but in a court appearance on Tuesday a judge changed that to no bond.
"He's born in El Salvador and he's originally from there. It looks like he is a U.S. citizen currently, but there's obviously a concern that he might be a flight risk," said prosecutor Bill Exley.
Prosecutors say Alvarado initially denied having anything to do with his wife's disappearance, even joining the search for her this past weekend.
Alvarado is charged with murder, but his attorney says Alvarado may not be mentally competent to stand trial.
