A New Year’s Eve standoff between Jefferson County sheriff’s deputies and a gunman and a second nearly identical incident three days later both ended in suicide, sheriff’s officials said. Jefferson County sheriff’s officials told residents in the 6500 block of South Weber Street, near Woodmar Square Park in Littleton, to shelter in place on the afternoon of New Year’s Eve as deputies responded to an armed barricade. About three hours after the alert went out, sheriff’s officials said the barricaded gunman had killed himself. Sheriff’s officials announced a second shelter-in-place order — this time, for the 12000 block of Critchell Lane in Conifer — around 3:30 p.m. on Friday. About two hours after the order went out, for the second time in four days, sheriff’s officials announced that the armed man had killed himself and lifted the shelter orders.
