"After a while I believed him," Lindbergh Williams said, later adding that his father "embedded this in my head."

Returned to mother

Carol Williams won the return of her son. And, Lindbergh Williams said, it took his mother six months to rid him of those ideas.

Lindbergh Williams also said he didn't question it when his father introduced Malvo to him "as my brother," because "I know what kind of man my dad was."

Asked by defense lawyer Thomas Walsh if he loves his father, he replied, "Of course."

The defense has scheduled for Lindbergh and Carol Williams a return trip to give Lindbergh Williams an opportunity to visit his father in the Prince William County Detention Center.

Convicted of capital murder in the Oct. 9, 2002, fatal shooting of Gaithersburg engineer Dean H. Meyers at a gas station north of Manassas, Va., Muhammad, 42, was sentenced to death last week by a Virginia Beach jury.

Yesterday's appearance by Williams and her son on behalf of Malvo - neither testified in Muhammad's recent trial - marks the most powerful testimony the defense has placed before jurors so far.

It also marks the defense's shift away from Malvo's childhood in the Caribbean to trying to show that Muhammad changed him into a killer. Malvo is pleading not guilty by reason of insanity.

He is charged with two potential death-penalty murder counts in the fatal shooting of FBI analyst Linda Franklin, 47, who was felled Oct. 14, 2002, in the parking lot of a Home Depot store in a bustling shopping area of Fairfax County.

One count accuses Malvo of multiple murders within three years. The other, under Virginia's untested anti-terrorism law, accuses the Jamaican-born youth of scheming to extort $10 million from the government to end the shootings.

Stay in shelter

Seven other witnesses testified yesterday, the 13th day of the trial. All were from Bellingham, Wash., where Muhammad and Malvo stayed in the Lighthouse Mission homeless shelter.

Each described the teen-ager as subservient to Muhammad.

Muhammad arrived at the shelter Aug. 16, 2001, with the three children he had abducted from his estranged second wife in Tacoma, Mildred Muhammad. Workers said he doted on the youngsters. But two weeks later, the children were gone, returned to their mother by child protective workers.

The nine woman, seven-man jury was not permitted to hear what the Rev. Ronald Lee Todd, the shelter's chaplain, said Malvo confided one night about his hesitancy to convert to the Muslim faith.

He said Malvo told him "my leader said to me ... we'd like to take over America. Malvo said, when I heard that, I was not so sure I wanted to be a part of that."

Outside the courtroom, Malvo's lawyers said their client has left the Muslim faith.

The relationship between Malvo and Muhammad was evident even at a Bellingham coffeehouse where the two played chess and had "an intense type of conversation," said Peter David, who worked at Stewart's Coffee House.

David also said that Malvo took lots of honey from a large jar to make sandwiches, which he found odd.

"I'd never seen anybody eat that much honey before," he said.
