A man who fled as an immigration raid unfolded at a Home Depot in Southern California was killed when he ran onto a freeway as federal agents moved in, local officials said.

Roberto Carlos Montoya ran from a Home Depot in Monrovia, about 20 miles northeast of downtown Los Angeles, as Immigration and Customs Enforcement agents began the operation Thursday morning, Monrovia City Manager Dylan Feik said in a statement.

Hundreds gathered in Monrovia Friday night at a vigil for Carlos Roberto Montoya, who was struck and killed by an SUV while trying to flee U.S. Immigration and Customs Enforcement agents.
