Florida man's double life is exposed in the hospital when his wife meets his fiancée

In 2016 Jessica Devnani was dating Gregory Bender, a successful hedge fund manager, who lived near Orlando, Florida. What Jessica didn't know at the time was that Greg had been keeping a secret from her. The secret would be exposed while he was recovering from a medical procedure at a local hospital. What happened in that room would lead to events that would forever change lives.  

Devnani had met Bender online in 2009. He was 42 years old and Devnani was nearly 20 years his junior. "He had a very charismatic personality. He was very intelligent," Devnani said. "It felt like we'd known each other all our lives ... he became my best friend." 

As their romance developed, Devnani says she noticed Bender had a streak of jealousy in him and sometimes it would escalate to verbal threats. "I never feared what he could do to me, but I feared what he could do to other men," she said. Despite his flaws, she remained with him and eventually they got engaged. Devnani tells her story exclusively to "48 Hours," in "The Ring: The Murder of Patrick De La Cerda," reported by Peter Van Sant.
