CHESAPEAKE, VA. ? In a chilling audiotape played for the jury Tuesday, a soft-spoken Lee Boyd Malvo told police he pulled the trigger in all of the sniper attacks that terrified the Washington area last fall.

“I intended to kill them all,” said Malvo, then 17.

Malvo, now 18, is on trial on charges of murdering FBI analyst Linda Franklin, who was cut down by a bullet outside a Home Depot. He could get the death penalty if convicted. Ten people died and three were wounded during the three-week sniper spree in Washington, Maryland and Virginia.

Jurors were given transcripts because the sound was poor and Malvo’s voice was soft.

When Malvo’s interrogator, Samuel Walker, a detective with the Prince William County police department, asked Malvo whether he squeezed the trigger in all the shootings, Malvo first responded, “Basically, yeah.”

Asked to clarify, Malvo said, “In all of them.”

Walker focused on the Dean Harold Meyers slaying, eliciting through a series of questions that Malvo shot Meyers in the head because Meyers was standing sideways.

“His body twisted this way, so I couldn’t get a body shot,” Malvo said.

Walker testified Tuesday that Malvo was candid and cooperative and never appeared to be out of contact with reality during the conversation, which lasted an hour and 40 minutes.

Malvo’s lawyers contend Malvo is innocent by reason of insanity because he was brainwashed by Muhammad.

In nearby Virginia Beach, meanwhile, a jury heard more evidence Tuesday on whether John Allen Muhammad should get the death penalty for masterminding the attacks.

Muhammad was convicted Monday in the murder of Meyers, killed as he filled his tank at a gas station.
