Castillo said he did not know Vargas former Miami Dade College supervisors held similar suspicions that Vargas sent them inappropriate texts, emails and Facebook messages. Police were only able to trace the origins of those messages to a Hialeah public library.
Vargas arrived half an hour late to the deposition, scheduled for 10 a.m. in Castillos office conference room. Vargas wore a business suit, Castillo said, and was calm and courteous, drinking a couple of glasses of water from paper cups.
Mr. Vargas spoke softly and never raised his voice, Castillo said. He never refused to answer any of my questions. He never made any threatening comments.
At first, Vargas denied making the threats. But after several hours, and after Castillo suggested Vargas might be perjuring himself, Vargas owned up to the messages.
It wont happen again. I swear to God. Soy un idiota, Castillo quoted Vargas as saying.
Castillo asked Vargas to promise never to engage in similar behavior and to draft a letter of apology to Bullet Line employees.
Vargas agreed. Four hours later, he sent the letter, riddled with grammatical errors, via email to Castillo.
This is the hardest letter I have ever written, Vargas began.
I feel I owe you a personal apology for my insensitive comments, disrespectful and deceiving mails. I accept full responsibility for what happened, he wrote. The main reason, I believe it is, I was sad to stop seeing you guys, enjoying lunch in your company and not been able to participate at the new place. Dont believe me, but I am pouring tears right now.
Bullet Line had moved to Hialeah from Miami shortly after Vargas left the company.
Three days after the deposition, Vargas showed up at Castillos office again, unannounced and in casual attire. He told an administrative assistant that he wanted to speak to Castillo about his deposition. When he learned the attorney was out of the office, Vargas left, without leaving contact or any other information. Its unclear if he carried the Glock 9mm semiautomatic pistol he legally purchased in 2010.
He did not make any hostile or threatening remarks of any kind, Castillo said.
Since Fridays shooting, Castillo has met with Hialeah homicide detectives, he said. Bullet Line representatives have also been interviewed.
Vargas told the attorney he had never been fired which appeared to be true, because he was forced to resign from his job in Miami Dade College North Campus media services department in 2008 when he learned of his imminent dismissal.
MDC began termination proceedings after an investigation into Vargas prompted by his poor work performance found he had downloaded a slew of inappropriate files onto his office desktop, including a so-called Anarchist Cookbook, which includes instructions on making explosives at home, counterfeiting money and killing someone with your bare hands.
He also downloaded other files, listed as apparent Internet browser searches, titled Easily Hypnotize Anyone, Secrets of Speed Seduction and The Complete Idiots Guide to Amazing Sex, according to his personnel file.
Vargas denied the MDC allegations against him, characterizing them in a Dec. 4, 2008, email to his supervisor as an attempt to smear my good name and reputation.
