Reyes was reported missing after she failed to show up to work on January 29 in New Rochelle, New York and her body was found on February 5 stuffed in a red suitcase.
"Together with our partners from the Greenwich and New Rochelle Police Departments, we were able to swiftly identify Javier Da Silva, an alleged murderer, and place him behind bars", FBI Assistant Dir.
Remarkably, the victim's mother Norma Sanchez said that she had a conversation with her daughter the night before she disappeared.
"Multiple crime scenes had been examined, hundreds of hours of surveillance footage had been reviewed, and numerous interviews of potential witnesses had been conducted", Berry said. "I'm paranoid, mommy. I'm getting anxiety attacks'".
A week-long search ended with a grisly discovery on the side of a highway in Greenwich, Connecticut last Tuesday.
Investigators "saw continued ATM activity and that's what zeroed us in", Berry said.More news: Usher And Rich The Kid Involved In Studio Armed Robbery

Sanchez says she desperately tried to pry for more information, but her daughter refused to specify why she felt that way.
Reyes, who worked at a Barnes & Noble in Eastchester, N.Y., planned to train to become a tattoo artist and liked to sing.
"I'm afraid someone is going to murder me", she recalled her daughter saying. "I just feel so blessed, overwhelmed". He said, "Every suitcase body I ever had they were known to each other, with the exception of the Mafia", calling it an "interpersonal type" of killing. "Was there someone at your house?' Reyes" mother said.
William F. Sweeney Jr., head of the FBI's NY office, said federal authorities teamed with police in Greenwich and New Rochelle to "swiftly identify Javier Da Silva, an alleged murderer, and place him behind bars".
Reyes was identified last week as the person whose body was found jammed into a piece of luggage abandoned in upscale Greenwich, Conn. Reyes' cause of death was not immediately clear.
"At this unimaginably hard time, we are asking for love, support and respect to our family for the loss of my handsome daughter Valerie Reyes who is now resting in heaven", he said.
Reyes lived alone in a basement apartment in New Rochelle and suffered at times from anxiety and depression, WABC reported.
