A Thornton police officer answering a call of a man wielding a
bat and knife tried to stop the suspect with a taser Friday
night, but when that failed his partner shot the attacker to
death, authorities say.    Police were called to 2642 East 98th
Place around 7:30 p.m. after the suspect allegedly threatened
neighbors with the bat and knife and was yelling, Barnes said.
Immediately after the two officers arrived, the man charged
after them, swinging his bat, Barnes said.
