Boston Police Commissioner William Gross held a meeting on Tuesday with managers of local night clubs and Boston city officials to discuss the best practices to keep inebriated patrons safe after the kidnapping and death of 23-year-old Jassy Correia, who was found dead on Feb. 28 after being taken from a Boston nightclub days earlier.

"This is all to just send the clear-cut message that enough's enough. There are predators out there. There are hunters out there," Gross told reporters after the meeting. "And we want to show folks now that we are working together collaboratively. There will be no gaps in service."

Gross said the most important thing is for local establishments to adopt technology devoted to the safety of their patrons, including driver's license card readers and surveillance systems. He pointed out that in both Correia's case and in the case of 23-year-old Olivia Ambrose, who was found alive after being abducted from a Boston bar on Jan. 19, surveillance video was crucial in apprehending suspects.

"It's a common-sense approach," Gross said. "Too many tragedies."

The commissioner also emphasized the need for clubs to be extra vigilant around closing time, and that they should reach out to police if they believe a patron is dangerously intoxicated instead of just kicking them out.

"This is a unified front here," Gross said. "We've committed to having a working group and/or committee to further our discussions here so that we have the voice of not only the licensed premise owners, but as well, the licensing board and BPD, and our law enforcement and first responder families."
