Police will once again question DC sniper Lee Boyd Malvo, after the convicted serial killer said for the first time in a TV interview with actor William Shatner that two other men were initially part of the bloody plot that terrorized the Washington area and left 10 people dead in 2002.
"There were two others, there were two other people who were supposed to be involved - but in the end, they ended up backing out," said Malvo, who was 17 when he was arrested for his role in the deadly attacks. He spoke to Shatner, most famous for his role as Capt. Kirk on the 1960's TV show "Star Trek," via telephone from a Virginia prison where he is serving a life sentence.
"What was supposed to happen was that there was supposed to be three to four snipers with silenced weapons, silenced rifles and in this way you could do a lot more damage along the entire Eastern Seaboard then what-- in the end there was only Muhammad and myself," Malvo, now 25, told Shatner.
Together Malvo and John Allen Muhammad terrorized the DC metro area, shooting 13 people at random and killing 10 of them during a three month crime spree.
Officials at the Montgomery County Police in Maryland, who first learned of the details of the interview from ABC News.com, said they would "definitely" send detectives to re-interview Malvo in his prison cell in Virginia.
"We will definitely follow up on this information," Asst. Chief Drew Tracy, who led the investigation at the time told, ABCNews.com. "We have no knowledge of any accomplices in the Washington DC area."
Tracy said investigators had recently interviewed Malvo regarding a possible connection to a series of crimes prior to the DC shootings. He could not comment on the specifics of those cases because they remain under investigation.
Malvo told Shatner two others planned to help with the killings but they backed out and at least one was killed, according to the Associated Press which viewed the episode.
Over the course of the interview Malvo's story about the additional snipers changed. He first denied their existence and later said a man in Arizona was supposed to help acquire weapons and another in New York was to help them get out of the country "when it's all said and done."
Since his arrest Malvo's statements have been inconsistent, and authorities have cast doubt on some of his reported confessions following his imprisonment.
John Allen Muhammad, 48, who masterminded the serial murders and whom Malvo's defense lawyers claimed had brainwashed the young man, was executed by lethal injection in November 2009.
In the one-hour interview, "Confessions of the DC Sniper with William Shatner: An Aftermath Special," Malvo also claims the duo shot more than just the 13 known victims in the DC area.
Malvo Forgives Himself
"I have seen and have been on the end of either watching someone die or killing someone in so many different circumstances. Mowing their lawn, out with their family. And at any time, you can die," Malvo said, without specifying exactly how many.
One prosecutor is wary of Malvo's new claims regarding the additional gunmen and the additional shootings.
"I don't know that you can trust anything Malvo says," Prince William County Commonwealth's Attorney Paul Ebert said.
Chief Tracy said Malvo had been inconsistent early on, but after his sentencing had provided investigators with credible information.
"Malvo has been pretty forthcoming and credible ever since he's beein in prison," Tracy said.
Malvo told Shatner Muhammad took him in and trained him when he was a teenager to be a coldblooded killer.
"He would send me to do a crime and then he would watch the crime and then he would evaluate me after I would finish and we'd work on the next time what was wrong, what I needed to change, emotionally, in my approach, in my tactics," Malvo said of Muhammad, a man his defense lawyers once called a "monster." Shatner told "Good Morning America" Thursday that he believes Muhammad brainwashed the teenager.
"He was a malleable teenager and lacking love in his life," Shatner said. "John Muhammad supplies the love and influences him to become a killer, and he becomes a cold-blooded killer at the age of 17. Now he's in jail and now he begins the turmoil in his mind."
Malvo, who lives in segregation at a maximum security prison, told Shatner he has forgiven Mohammad and himself.
"This is going to be surprising, but I've had to forgive him in the same way in which I've had to, over time, gradually forgive myself," Malvo said. "Every day I get up, somebody's wife, child, husband is not going to come home tonight. There is nothing that I can say or ever do that will ever change that fact."
