DORAL, FLA. (WSVN) - The family of a Doral mother and her daughter are making a plea for help months after their disappearance.

Police said they have hit a roadblock after trying for three months to figure out what happened to Liliana Moreno and her daughter, Daniella.

They have handed out flyers hoping to generate new leads.

Miami-Dade Police have suspected foul play in this case after they were called to the Doral home by Moreno’s sister, who lives in Colombia, when she was not able to get in touch with the 43-year-old mother. “We need to know what happened to my sister and my niece, and we need information about that,” said Moreno’s brother, Eduardo Ramirez.

The mother and daughter went missing on May 31. When investigators searched her Doral apartment, they found her purse and keys. The front door was also locked, and her car was in the driveway.

“If this turns out to be a death case, if it turns out to be that, we need every little piece of information to put it together,” said Miami-Dade Police Assistant Director Wilfredo Ramirez. “It is an 8-year-old little girl. Look how this family is suffering right now. Give us whatever information you have.”

Police have named the little girl’s father, Gustavo Castano, a person of interest. In June, police found the dad stabbing himself in the throat inside a truck in the parking lot of a Hialeah Gardens Home Depot.

Castano lost an eye in a Taser fight with police, but officials have yet to arrest or officially connect him to the disappearance. “He was the last person who saw my sister and my niece,” said the brother. “I think it is incredible that he don’t worry.”

With the lack of eyewitness accounts of that day, police are having a tough time piecing together a timeline. “There are minimal witnesses,” said assistant director Ramirez. “We are asking people to come forward. We need a timeline, and we need to fill those gaps.”

The attorney for Castano has told 7News that his client has been nothing but cooperative during the investigation, doing hours of police interviews. The attorney also noted that Castano did not hire any legal help until the Taser incident.

If you have any information on the whereabouts of Liliana Moreno and her daughter, call Miami-Dade Crime Stoppers at 305-471-TIPS. Remember, you can always remain anonymous, and you may be eligible for a $1,000 reward.
