Javier de Silva was arrested on Feb. 12, a week after the suitcase was found in Greenwich.
Greenwich police Capt. Robert Berry said in a statement that detectives arrested a suspect in New York who had illegally used Reyes’ ATM card.
“The arrested individual is also believed to be involved in the death of Valerie. Additional information on the suspect and charges will be released by the New Rochelle Police Department,” he said late Tuesday morning.
Greenwich officials said that authorities examined multiple crime scenes, conducted numerous interviews, analyzed social media posts, and watched hundreds of hours of surveillance footage in the investigation.
According to Reyes’ mother, her daughter became paranoid and spoke to her about her fears on Jan. 28, the night before she vanished.
