A Kansas City, Kan., woman has been accused of leaving three children alone in a car in 40-degree weather while she gambled in a casino.

WDAF-TV reports that Katrina Denise Roades is charged with endangering the welfare of a child.

Police said Roades left the children, ages 9, 8 and six months, in a parked car while she went into the casino on March 3. A security officer found 1 of the older girls wandering in the parking lot. The child led the officer to the family’s car, where he found the other children.

Police believe Roades was inside the casino for about an hour and a half.

Roades also faces a trespassing charge because her name was on voluntary self-exclusion list designed as a tool for compulsive gamblers.
