He said there was a helicopter overhead in an unrelated matter and that he didn't like the idea.

Malvo admitted that he stole a map book from a Baltimore public library, identified by earlier witnesses as the Reisterstown Road branch of the Enoch Pratt Free Library - to find three schools whose buses the pair would follow.

He said they would learn where the buses were parked and Muhammad would plant explosives on the "soft spot" under each bus to kill children later while they were en route to school.

Malvo also said Muhammad had books on how to make explosive devices and had a plan to acquire explosives, including C4 plastic explosive. But Malvo said the Persian Gulf War veteran did not share the details with him.

The bombs that were to go off at the police funeral were to contain nails and ball bearings to maximize the damage.

Speaking in a low, breathy voice for five hours of direct testimony for the prosecution, Malvo laid the ever-changing plans to Muhammad, who he said initially told him that they were going to Maryland so that Muhammad could regain the three children he had lost to his ex-wife in a custody fight.

But in July 2002, Malvo testified, Muhammad changed it to a mission of terror, though the teenager suggested that they could just go to Clinton and whisk the children away from Mildred Muhammad.

"There was no reason, and when I asked, he would give me a look like, 'Shut up,'" Malvo said.

Malvo, who said Muhammad had been instructing him in Washington state for months at firing ranges by day and in anti-Americanism over their single daily meal, said he was devoted to Muhammad. The man had fed him, clothed him and brought him illegally from Antigua to the United States.

Malvo said that at Muhammad's behest, he knocked on Mildred Muhammad's door, so that Muhammad knew he had the right house.

From there, they went to New Jersey to buy a dark blue 1990 Chevrolet Caprice, which Muhammad modified into a sniper's lair with a gun port in the trunk and hatch to hide a shooter and weapon. They tested the plan with a robbery and shooting in Montgomery, Ala., before returning to Maryland, Malvo said.

Deputy State's Attorney Katherine Winfree led Malvo through a short version of his life in the Caribbean, where he was starved for parental attention and met Muhammad at the age of 15, through his arrest in Muhammad's car at the age of 17.

Malvo said Muhammad fired the Bushmaster rifle in 11 of the 14 shootings that he discussed. Malvo said he spotted for Muhammad, who fired from the homemade gun port in the trunk of the Caprice.

Relatives of several victims wept as Malvo matter-of-factly testified that he told Muhammad the shootings were a go and that Muhammad took the shots that felled their loved ones.

The wails of the widow of Premkumar Walekar, a cabdriver who was gunned down at an Aspen Hill gas station on Oct. 3, 2002, resounded in the courtroom as she was led out by relatives. Malvo admitted being the trigger man in three shootings, including one fatal shooting in Montgomery County.

That testimony was at odds with his statement to police when he was arrested, in which he took credit for pulling the trigger in all of the shootings. Muhammad, acting as his own lawyer, pointed that out later in cross-examination.

Malvo's psychologists testified at his 2003 trial that he told them he had killed two people, the niece of a woman who testified against Muhammad in his divorce and the final sniper victim.

Muhammad shot victims from inside the trunk of the car and directed Malvo to do all of the shootings outside of the car, Malvo testified. He said he dug shallow holes in the wooded areas and covered himself with branches as he waited for hours to victims to approach.

He shot 13-year-old Iran Brown in the abdomen on Oct. 7, 2002, as the teen headed into Tasker Middle School in Bowie; and Jeffrey Hopper in the abdomen on Oct. 19, 2002, outside the Ponderosa restaurant in Ashland, Va., he said. They survived and testified here in recent weeks.

Malvo said he spent the night before he shot Iran Brown in the woods outside the middle school. Asked by Winfree what he was thinking about at the time, Malvo said, "How I was trained, you control yourself and think of nothing but the mission."
