Pierce County prosecutors haven't yet decided whether to charge Lee Boyd Malvo and John Allen Muhammad in the shooting death of a Tacoma woman last year.
Malvo reportedly told two Maryland jail guards he had killed 21-year-old Keenya Cook in Tacoma on Feb. 16, 2002.
Cook was fatally shot when she opened the door of her aunt and uncle's home on East 34th Street. Cook's aunt, Isa Nichols, was friends with Muhammad's second wife and sided with her in the couple's child custody battle.
Prosecutor Gerry Horne has said if he has the evidence to charge Muhammad and Malvo, he'll consider the costs of transporting and trying them in Tacoma, given the fact that Washington would be behind other jurisdictions waiting to try them.
Horne's chief criminal deputy, Jerry Costello, has said they would also consider whether filing charges in Tacoma might delay imposition of the death penalty.
