LAS VEGAS — An arrest warrant is shedding light on the aftermath of an attack on a mother and two children last November in Las Vegas that later prompted an internal investigation by the local police department.

It took two months for prosecutors to charge Las Vegas resident Marcus Maddox on Jan. 18 with murder in his daughter’s death and attempted murder in his son’s attack, the Las Vegas Review-Journal reported. A week before he was charged, according to the warrant, the boy acknowledged through gestures “and limited verbal means” that his father attacked them.

The deceased girl and her severely injured brother were found Nov. 20 at an extended-stay hotel south of the Las Vegas Strip. That was roughly 17 hours after their critically injured parents were found at another hotel.

Police accused Maddox, 30, of severely beating the woman before shooting himself. He was charged with attempted murder and other counts in the attack on his wife.

Maddox, a convicted felon, is being held at the Clark County Detention Center. He has a preliminary hearing scheduled for March 1. His attorney did not immediately return a call from The Associated Press seeking comment Tuesday.

After the attack, police opened an internal investigation to determine why it took so long to find the children. Police at the time said that they made several calls to the Clark County Department of Family Services the night of the attack, but they were not returned until the next morning.

The warrant shows Child Protective Services employees found the girl’s body lying on the floor and her brother sitting nearby. Nobody answered the motel room’s door when officials knocked, so management used a master key to unlock it.

“She was cold to the touch and had no pulse,” a police officer wrote in an arrest warrant. The boy had a pulse and his breathing was shallow. He was taken to a hospital in critical condition with stab wounds and a broken skull.

The warrant states police discovered the children’s DNA on the blade of a knife found at the scene.
