Joshua Aaron Robertson, 27, and Brittany Humphrey, 22, were arrested Thursday without incident in Pueblo, about 40 miles south of Colorado Springs, according to the Los Angeles County Sheriff's Department. The couple was wanted in connection with the death of Humphrey's half-sister, Kimberly Harvill, whose body was found with multiple gunshot wounds along a road in a remote area of Los Angeles County on Aug. 14, the AP reports. Police say Harvill had been staying with Humphrey and Robertson and that all three were involved with methamphetamine. Investigators say the couple kidnapped Harvill's three young children, who were found safe Wednesday in a motel on the outskirts of Albuquerque. Humphrey and Robertson, who authorities had said should be considered armed and dangerous, were found after officers from the Pueblo Police Department were conducting an unrelated investigation at a local motel where they were staying, the sheriff's department says. Robertson's baby girl was found unharmed and is in state custody.
