Maryland State Police identified Baltimore residents Robert Vicosa, 41, and Tia Bynum, 35, on Thursday as two people found in a car Thursday afternoon that matched the description of the suspect vehicle involved in multiple felonies including child abduction and carjacking. Vicosa was an officer with the Baltimore County Police Department for 17 years, local station WGAL reported. He had reportedly been terminated in August after being demoted to an officer from a sergeant. Bynum had also reportedly worked for the department for 14 years. Two young children, who police believe are Vicosa's daughters, were in the car as well. Vicosa, Bynum and one of the girls were pronounced dead on the scene; the other young girl was taken by medevac to Meritus Medical Center in Hagerstown, where she was pronounced dead. Earlier in the day, police had launched a manhunt for Vicosa and Bynum, who they said were armed with "at least one handgun and possibly several semiautomatic rifles." The pair had allegedly robbed and kidnapped a person in Cockeysville, Baltimore County, police said. Two Charged For Crash That Killed N.C.
