Peter Lucas Moses on Monday pleaded guilty to killing a 4-year-old boy he believed was gay and a 28-year-old woman.

Prosecutors say they'll seek the death penalty for Moses of Durham, North Carolina. He faces first-degree murder charges in the deaths of 28-year-old Antoinetta Yvonne McKoy and Jadon Higganbothan, 4, WRAL reported.

Moses, 27, prosecutors say, led a “religious” group of five women and nine homeschooled children, all of whom lived with Moses, the father of all the children except for Jadon. The AP identified Moses' sect as the Black Hebrews.

Vania Rae Sisk, 25, had been told by Moses to “get rid” of her son, who Moses feared might be gay because his father had left Sisk.

Moses, it is alleged, became angry sometime in October 2010 when he found out that Jadon had hit another child's bottom. He ordered the women to set up computers and speakers in the garage, then took Jadon in the garage and shut the door. With religious music playing, the women heard a gunshot.

He is accused of killing McKoy in December of the same year after he learned she was barren and wanted to leave the group.

One of the women escaped the house and told police that the remaining three women encouraged Moses to kill McKoy because they feared him going to jail. The three women also face first-degree murder charges in McKoy's death and as accessories to murder in Jadon's death.
