A mother in Florida is accused of leaving her three children home alone to go have sex with the neighbor.

Crystal Rusaw, 24, was arrested on charges of child neglect, Tampa Bay TV station WTSP reported.

The children -- ages 10 months, 3 and 4 -- were left in their New Port Richey home for about four hours. Witnesses called police after seeing them crossing a busy street at 5 a.m. Sunday.

The 4-year-old was holding the 10-month-old, who had a wet diaper, as the trio dodged traffic.

"It could have been tragic," neighbor Joan Miller told Tampa Bay TV station WFTS. "It's just unbelievable."

Deputies said Rusaw admitted to her crimes when arrested. The neighbor authorities said she was visiting was not identified.
