AUSTIN CARTER: Five agonizing years is how long the family of Liliana and Daniela Moreno have been waiting for the truth about the disappearance of the mother and daughter. One person of interest remains, Gustavo Costano. He was Liliana's ex-boyfriend and Daniela's father, and according to police the last person to see them alive. Liliana's brother says Gustavo is responsible.

EDUARDO MORENO: Only person who knows what really happens is still there. [INAUDIBLE] next to you. Living his life the way that he wanted and doing what he want to do.

AUSTIN CARTER: Liliana and Daniela were last seen on Memorial Day 2016. They live near Northwest 41st Street in the turnpike in Doral. Gustavo told investigators then he dropped them off at a Home Depot along Okeechobee Road in the turnpike. In the same area, police had a confrontation with Gustavo after he stabbed himself in the neck. Police had tasered him, and he lost his right eye as a result. He has denied any involvement in the disappearance of Liliana and Daniela.

CHRISTOPHER VILLANO: He's out in the community here in South Florida.

AUSTIN CARTER: But now, local agencies along with the FBI are trying to turn up the heat on this cold case. Miami-Dade Police Detective Christopher Villano says they need new leads and evidence.
