Over a decade has passed since Delcia’s death, and police have not made any arrests in connection with her murder. However, a detective working the case has stated that Raul is a suspect in the case. He has been reportedly been “extensively questioned”, but he has never been charged with anything related to the case. However, the detective also stated that they are open to exploring other suspects as well. He explained, “even though common sense dictates that we look at [Raul], I don’t want us to be oblivious to anyone else. I don’t want the people out there to focus all of their attention on Mr. Mata. If there is any bit of information out there that will lead us to another individual, I am all ears” Despite this, though, Raul has still not been ruled out.
A murder weapon was never found, but detectives reportedly have DNA that could lead to a suspect. They are hoping that the advancement in DNA technologies could help them identify the killer. Meanwhile, investigators are encouraging anyone with information that could help solve Delcia’s case to contact Miami-Dade Crime Stoppers at (305) 471-TIPS (8477)
UPDATE (9/27/20): Raul Mata has been arrested and charged with Delcia's murder. The arrest was made after investigators were able to use new technology to match DNA found under Delcia's fingernails to Raul. This type of technology was reportedly not available to investigators back in 2004 when the murder occurred.
Investigators believe the murder occurred after Raul made several inappropriate sexual advances towards Delcia. He later separated from Delcia's mother and moved to California where he started a new life with a new wife and children. Authorities were able to track Raul down, and he was arrested in California on September 26th, 2020.
