Childers sent a letter and audio tape to the Clarksburg Police in May, admitting to murdering two women.

Police later identified those women as Carrie Lynn Baker, 26 of Clarksburg, and Carolyn Sauerwein, 40 of Philippi.

One agent is from the FBI's behavioral analyst unit while the other is from the National Center for Analysis of Violent Crime.

Clarksburg Detective Mike Walsh took the agents to the Childers family farm in Flower, where Sauerwein's body was found, according to Lieutenant Robert Matheny.

They also visited the site in Barbour County where officers found Baker's body, Matheny says.

The agents have reviewed the tape and letter Childers sent, according to Matheny, and plan to analyze two deaths from 2004 that Clarksburg Police believe may be linked to the case.

The identities of those possible victims are not being released, as police are unsure that they are related to Childers.

The FBI has not given its official report.

Instead, agents will review the new information, and plan to have their report completed by the end of July, Matheny states.

Clarksburg Police received the envelope from James Childers, which contained handwritten notes and a two-hour audio tape on June 1.

In them, Childers admitted to five murders and four arsons.

Police later found evidence of the murders of Baker and Sauerwein, but as of yet, have been unable to find evidence of the other three Childers mentioned.

The four fires Childers set were on Northcott Street in Clarksburg, where Childers used to live.

In fact, police believe Childers set fire to his former home just one day after selling it, to conceal the evidence of Baker's murder.

Childers killed Baker by hitting her in the head with a blunt object in that Northcott home, police say, before Childers left her body at a dumpsite off Route 57 just inside the Barbour County line.

Sauerwein died from two gunshot wounds to the head, which the authorities say happened on the farm in Flower.
