Deputies said they were dispatched to the 8400 block of Jeske Road in Needville after receiving a report of a dead man seen hanging from a tree.
Officials have tentatively identified the man as homicide suspect Jhon Vanegas Romero, 24, based on his clothing, tattoos, and a passport found on him.
Romero had been a key suspect in the homicide investigation of his wife, Anyi Montealegre Izquierdo, 23, who was found stabbed to death in their home on Monday, which prompted an active manhunt.

His body was found approximately two miles northeast from the location Romero was last known to be, authorities said. The vehicle he was last known to be driving was located and recovered in the same area.
Romero's body has been transported to the Fort Bend County Medical Examiner's Office for examination and identity confirmation.
