A Colorado woman who reported seeing a young boy left alone in a hot car was allegedly run over by the child's mother -- and must now use a wheelchair.

Shannon Dominguez, 43, and her boyfriend called 911 after observing a small boy left alone in a hot vehicle outside a store in Longmont, Colo., Fox affiliate KDVR-TV reported.

When police arrived, however, it was Dominguez who needed an ambulance.

The child's mother, identified as 27-year-old Kristina Riddell, reportedly became enraged when she heard the couple on the phone with police.

Riddell allegedly punched Dominguez's boyfriend, Alan Mason, before running the couple over with her white Honda.

"All four windows were rolled up. And it was in the direct sun. It scares the heck out of me. It’s some innocent child might die," Dominguez told the station.

The incident, which occurred June 7, left Dominguez so badly impaired that doctors say she may never walk again.

"Every day is a chore. Every day is stressful," said Dominguez, whose left leg was crushed.

Riddell is facing charges of hit-and-run, assault and child abuse.

She has an extensive criminal record, including arrests for assault, domestic violence and multiple driving violations, according to the station.
