A UPS employee accused of killing a co-worker in a truck has confessed to the crime. Elijah David Bertrand, 19, of Bristol was helping Nathan Burk, 28, to deliver packages when he attacked Burk. According to his arrested warrant, Bertrand said ’What took you guys so long to find me?’ when he was captured. A motive for the murder is still to be established. Bond for Bertrand was kept at $2 million.
