He is also a suspect in a number of other robberies and crimes from Chicago into Wisconsin.
Douglas is a wanted man by local, state and federal law enforcement agencies. Considered armed and dangerous, police say Douglas is responsible for three weekend carjackings.
The second occurred Friday right after he crashed a stolen car into a vehicle, in which Donovan Turnage was a backseat passenger.
As Donavon's relatives grieved at the boy's South Side home Sunday family members had something to say to this man.
"Just turn yourself in cause you took an angel from us," aunt Lorraine Hicks said.
"I pray he gets caught and get what he deserves," said cousin Ashley Hicks.
Douglas is wanted for a weekend crime spree that resulted in Donovan's death. Police say Friday, Douglas stole a minivan on the North Side. Officers caught up with him Saturday near Garfield Blvd and S. Halsted. As they tried to pull Douglas over, he crashed into a suburban. Donovan was a passenger in the back seat.
"He was out with his father and brother getting a haircut for Christmas, they were supposed to come back and put up tree for his grandmother," said uncle Anibal Vega.
Donovan was thrown from the suburban and died a short time later at the hospital.
"He was the life of the party," Lorraine Hicks said. "There is nothing we could do, holiday, whatever we had, everybody laughing joking clowning around."
Donovan was known for his sense of humor in school, as well. He was a 5th grader at Morrill School. A day before he was killed, Donovan posed with the entire school wearing matching sweatshirts. Teacher Jennifer Gladkowski says the 11-year-old had a larger than life personality.
"Everyone knows him," she said. "He is the kindest, most generous happy-go-lucky, funniest. He touched a lot of lives."
Monday there is a 3 p.m. vigil planned at Morrill Math and Science Academy.
After the crash that killed Donovan, police say Douglas carjacked another person at a nearby gas station. A few hours later, that car broke down.
Police say Douglas carjacked a motorist trying to help him. Douglas may be driving a light blue 2007, 4-door Honda Accord, with an Illinois plate X144777
