Boyton Beach Police arrested 66-year-old Roberto Colon for first-degree murder Friday in the death of his wife, Mary Stella Gomez-Mullet, who went missing on Feb. 20. 

Officers originally searched Colon's property on Feb. 21 after a friend told them that she was on the phone with Gomez-Mullet just days before she went missing and it sounded like someone attacked her, WPEC reports

As detectives were leaving Colon's home that day, he reportedly shouted at them that his wife was "swimming with the fishes" and they needed to "find the body, find the body," according to the local news station.
