This is as prosecutors are building their case against Cid Torrez, claiming he killed his wife Vilet in a jealous rage back in 2012 in their Miramar townhome.

Crime scene investigator Michael Kelly says Cid Torrez’s blood was found under a sink on a pipe and elsewhere indicating a struggle.

“When you find small blood stains on the wall, remember you’re looking at a scene, something that’s not normal, trying to find indication that the crime scene occurred in the residence,” said Kelly.

Late Monday, Cid Torrez listened attentively as an audio tape of his police interrogation was played. You could hear the anguish in his voice as he denies knowing anything about his estranged wife Vilet’s disappearance.

On the same day, a business associate testified Torrez told him he secretly installed spyware on Vilet’s phone so he could track her moves.

“He said she’s cheating on him, there’s another guy,” said Christian Roman, a business associate of Torrez.
