A Boca Raton, Florida mother passed out in her van with her 5-year-old child in the back seat, police said.

“I just want to go to school,” the child cried out to first responders pulling up.

Boca Raton Fire Rescue administered Narcan, an opioid reversal medicine, and the mom, Colleen Nichols woke up. She is accused of overdosing on heroin.

She “responded positively to Narcan, and that only means one thing,” a Boca Raton Fire Rescue Chief said in a report.

Nichols denies using drugs, telling West Palm-based WPTV that she was not on heroin. She claims she suffered a panic attack.

“I don’t know, I must have blacked out. I’m under a lot of stress,” Nichols told officers at the time.

A man called 911 when he saw a small child crying Monday morning inside the van with the doors and windows closed, not running.

“Mommy keeps falling asleep and not waking up,” the girl said.

Records show the girl turned five the same day.

Nichols was taken to a Boca hospital and was arrested. She’s being charged with child neglect.

Police officers agreed with fire rescue saying in the report that since she positively responded to Narcan, Nichols “was more likely than not, unconscious due to heroin use.”

She was released from the Palm Beach County Jail on $1,000 bond.
