Four counts were filed against Chanton Jenkins, 32, of Houston, Texas, according to Houston police spokesman Kese Smith.

A fifth child who was in the car, a 3-year-old girl, was missing Sunday and is believed to have drowned also, police said.

Jenkins was driving a Lincoln Town Car during a rainstorm with six children and his brother as passengers when it went into the Green Bayou on Saturday, police said. Jenkins, his brother and one child escaped.

Of the five who died or was missing, three were Jenkins' children, and the other two were friends of the family, Smith said. Jenkins also is the father of the surviving child, Smith said.

Jenkins failed a field-sobriety test at the scene of the crash and a blood test was taken, Smith said.

Jenkins' brother told police the car went into the bayou just after Jenkins completed a phone call from the car.
