Bail was set at $4,000 Monday for Romanie Pierre, 31, and Malory Pierre, 27, both of North Miami, the South Florida Sun-Sentinel reported. They were arrested late Sunday on charges of child neglect.
Broward County Judge John Hurley said another patron of the Mardi Gras Casino noticed four children alone in a car and called 911. When police arrived, the oldest child unlocked the door.
The sisters told police they had only used the restroom at the casino, the arrest report said. But it turned out they had registered at the Players Club.
The children are now being cared for by their grandmother. Hurley said he would allow the sisters contact with the children.
"Hopefully these two have been scared and ... shocked into coming to their senses that what they have allegedly done is extremely poor judgment, and I'm not going to take their kids away," Hurley said during Monday's hearing.
