Baltimore County Police say 27-year-old Joshua Green started his Sunday shooting spree by going to his parents’ home in Baldwin and killing both of them.  They were discovered later when police went to notify them of their son’s death.  After killing his parents, Green then went to the Royal Farms location in Essex at about 6:45 a.m. and opened fire again, killing two customers and seriously wounding a store employee.  After the store shooting, police got the call to an apartment fire in the 14-hundred block of Shady Tree Road, near the Royal Farms, and found Green in the parking lot with a gunshot wound.
