A man who caused a crash that killed a Texas volunteer firefighter and his two children last week reportedly was in the U.S. illegally.

A Texas Department of Public Safety spokesman told the Dallas Morning News Tuesday that a van driven by Margarito Quintero, 33, swerved into the northbound lane on State Highway 70, hitting fire Capt. Peter Hacking’s car. Quintero didn’t have a license.

Hacking and his children – ages 4 and 22 months – died at the scene of the accident. Quintero and two others who were in the van were taken to Baylor Regional Medical Center in Plano with serious injuries.

DPS spokesman Lonny Haschel told the paper Tuesday that Quintero could be charged with criminal negligent homicide by the time officials complete the investigation of the accident.

According to U.S. Immigration and Customs Enforcement, Quintero is a Mexican citizen who entered the U.S. illegally near Laredo in August 2006. He was arrested on criminal charges and deported in 2008.

ICE said it has no record of encountering Quintero since his 2008 deportation. ICE spokesman Carl Rusnok told the Morning News an immigration detainer will be placed on him if he’s placed into custody.

A GoFundMe page was setup for Hacking’s family to help with funeral costs and other expenses for his children. As of early Thursday more than $20,000 had been raised.
