CLEMMONS, N.C. — A third person has been charged in connection with the deaths of two unidentified bodies discovered in shallow graves Sunday in the backyard of a Clemmons home.

A couple was first charged Sunday with murder and accessory after the fact — Pazuzu Illah Algarad, 35, and Amber Nicole Burch, 24, who lived at the house, along with Algarad’s mother, Cynthia Lawson.

Deputies said Tuesday that a third person has been arrested.

Krystal Nicole Matlock, 28, of West Fourth Street in Winston-Salem was charged with accessory after the fact.

Matlock is accused of helping Algarad bury an unknown man in a shallow grave in the backyard at 2749 Knob Hill Dr., the warrant said.

Matlock was placed in the Forsyth County Detention Center under a $250,000 bond. Her court date is Oct. 23.

Deputies responded to the house Sunday with a search warrant to search the property.

On the front door of a house where the skeletal remains of two people were found Sunday was a sign warning law-enforcement not to enter.

“No gang members allowed: anyone that dresses the same, has the same badge and call themselves the authority of the land they did not create…,” the sign said. Below and to the right is a picture of a skull and cross bones. Under that picture are the words, “Evil will triumph.”

Few details have emerged about what led authorities to the house on Sunday and what they have found, beyond the skeletal remains.

According to the Winston-Salem Journal, Pazuzu Algarad was born in San Francisco as John Alexander Lawson. Lawson changed his name to Pazuzu Algarad in 2002 for religious reasons. Pazuzu is the name of an Assyrian demon whose name was used in the movie, “The Exorcist.”

The house, owned by Cynthia Lawson and her ex-husband, Johnny Larry James, had been searched before in 2010.

In 2010, the sheriff’s department executed a search warrant at the house. Judge William Z. Wood of Forsyth Superior Court sealed the search warrant on Feb. 26, 2010. The search warrant remains sealed.

In 2010, Algarad was charged with accessory after the fact of involuntary manslaughter in connection to the shooting death of Joseph Emmrick Chandler.

Chandler had been reported missing and his body was found June 7, 2010, at Donnaha Park near the Yadkin River. He had died from a gunshot wound.

Nicholas Pasquale Rizzi of Lewisville was charged with involuntary manslaughter.

Rizzi was convicted of that charge on March 31, 2011, and sentenced to one year and one month in prison. Algarad was convicted in 2012. He was on probation from that conviction when the bodies were found Sunday.

Chief Deputy Brad Stanley would not say what led investigators to the house Sunday morning.

In 2010, Algarad was accused of choking his mother, and in court papers, his mother told law enforcement that she was afraid of her son but didn’t want to prosecute.

According to a secured bond findings form, law enforcement had said Algarad had performed satanic rituals and animal sacrifices at 2749 Knob Hill Drive on a regular basis. Algarad pleaded guilty on Aug. 23, 2011, to misdemeanor assault on a female and was placed on probation for 12 months.

Burch was also accused of assaulting Algarad’s mother in a separate incident. According to an arrest warrant for simple assault, Burch was accused of pushing, slapping and attempting to choke Cynthia Lawson on Sept. 22, 2011. She was convicted and sentenced to 12 months probation. Two months later, she was charged with assault and battery, with police alleging she struck Algarad in the face.

In their first court appearance Monday, Algarad and Burch told Forsyth District Judge Gordon Miller that they wanted court-appointed attorneys to represent them. Miller assigned capital defenders to represent them. Miller also told the two that if convicted, they could receive life in prison without the possibility of parole or the death penalty. Their next court date is Oct. 23.

Alagard and Burch were being held Monday night in the Forsyth County Jail with no bond allowed, court officials said. Matlock also was being held in jail with her bond set at $250,000. All three are scheduled to appear in court Oct. 23.

Stanley said Algarad and Burch dated and apparently were married in some kind of ceremony. But investigators have found no legal documentation stating that the two are married, Stanley said.

He said he has no idea how long it will take to identify the bodies.

The remains were transported to Wake Forest Baptist Medical Center for examination and positive identification.

Stanley said investigators are also looking at any missing persons reports.
