Man struck and killed by tractor trailer while running from ICE agents in St Augustine, police say

A man running from an encounter with immigration and other federal agents in Florida was struck and killed by a tractor trailer on Tuesday, authorities said.

The 28-year-old was among four occupants of a vehicle that stopped in the parking lot of a gas station and convenience store in St. Augustine before 7 a.m.

During an encounter with agents from U.S. Immigration and Customs Enforcement as well as Homeland Security Investigations, the four fled on foot, with one darting across a busy road into the path of the semi, Florida Highway Patrol Sgt. Dylan Bryan said in an emailed statement. The driver of the semi stopped and tried to help the man, Bryan said.

It was the third death in about a week involving encounters with ICE agents, following shootings in Texas and Maine.

The Department of Homeland Security issued a statement to CBS News about the incident that reads: 

"On July 14, DHS law enforcement conducted an operation near St. Johns, Florida. Florida Highway Patrol and HSI are investigating an incident resulting in the death of a Mexican national. We will provide an update when available."

No additional information about the man has been released.
