Twenty-seven-year-old Manuel Gutierrez Vazquez of Camden initially was charged with death by auto and two counts of assault by auto stemming from the crash on Route 29 in Hamilton that killed 28-year-old Jorge DeLeon and seriously injured his two young children.
But one of the assault by auto counts was upgraded to death by auto after DeLeon's 4-year-old daughter Jasmine died this week from injuries she suffered in the crash.
DeLeon's 7-year-old son is expected to recover from his injuries.
Authorities say Vazquez was driving drunk and traveling in the wrong direction when he crashed into DeLeon's vehicle. Vazquez suffered an arm injury in the crash.
