2-year-old in critical condition after being accidentally run over

A 2-year-old boy is in critical condition after being accidentally run over. 

The Hillsborough sheriff's office says Zachary Ustaszewski was in his stroller in a driveway when a neighbor backed up his truck and ran over him. 

It happened Sunday afternoon at Sandy's Mobile Home Park in Gibsonton. 

The driver, 28-year-old Brandon Concepcion, told deputies he did not see the toddler. 

Zachary suffered severe head trauma and was flown to Tampa General Hospital where he is in critical condition.
