morning, i m randi kaye. we start with the stand-off near seattle, a man accused of murdering his wife and daughter is holed up in an underground bunker. a swat team pumped in tear gas to force peter keller out. police are being cautious and patient. one friend of his wife is not being deliberate. i hope he resists. i want him to know what a bullet feels like. i can t stop being angry. now more from jim foreman. if this takes a day, month, week, we ll wait it out. most important is officer safety. reporter: as sunset nears, another swat team moves in to take up positions. first units have been at it since 5:00 a.m., commanders want fresh people. deputies now all but certain peter keller is in his deep underground bunker, a lair that could be bobby trapped. this isn t a whole in the ground, this is a large structure, hidden, took time to find it and in fact our tactical team smelled the wood smoke before they saw it. the break in the case comes straight out of csi.
