The Palm Beach County Sheriff's Office is investigating a deadly shooting that happened in the early morning hours.
Officials say two men were killed and two others injured after some sort of an altercation broke out between the coworkers of the 'Old Key Lime House' restaurant at the Rock Irish Pub in Lake Worth Beach.
Fellow co-worker Jackie Slattery tells CBS 12 News that they had all been at a company Christmas party nearby before heading to the pub to play pool.
"It's completely unnecessary. I mean, we're all out here just trying to have a good time, love eachother. Make the holidays a special time. It just wasn't worth it."
Two of the men were pronounced dead on the scene while two others were injured, one of them critically.
No arrests made yet. PBSO is investigating to determine who was at fault.
