(CBS) – Chicago and state police officials are still searching for a serial carjacking and robbery suspect blamed for causing a fatal traffic accident that killed an 11-year-old boy this weekend.

Police are looking for Rockie Douglas, a 34-year-old man they believe is responsible for the carjackings. Douglas may be driving a light blue, 2007, 4-door Honda Accord bearing Illinois license plate X144777.

Grieving relatives of the child, Donovan Turnage, remembered the boy as a bright fifth-grader and special young man.

“He was just too young to go,” the boy’s cousin, Richard Miller, told CBS 2’s Derrick Blakley on Sunday.

To the suspect who caused the crash, Miller said: “You just took an 11-year-old boy’s life before Christmas, and he was looking forward to Christmas.”

Donovan was riding in the family’s SUV Saturday around 12:30 p.m. when a stolen minivan crashed into the vehicle at Garfield and Halsted. The boy and his father were taken to the University of Chicago medical campus, where Donovan was pronounced dead.

The suspect blamed for causing the fatal accident hijacked another vehicle from a nearby gas station, state police say, before he embarked on a one-man crime wave that took him through the western suburbs.

The vehicle got flat tire shortly before 4 p.m. Saturday at Interstate 294 and Interstate 88. State police say the offender hopped out of the disabled vehicle and carjacked a 2007 light blue Honda Accord.

The Accord owner gave a description of a white male in his mid-30s, about 6 foot, three inches tall and 275 pounds, wearing a white hoodie.

State police say that fits the description of a subject who committed armed robberies in Oak Lawn and Burbank between the time of 12:30 p.m. and 4 p.m. Saturday.

State police said earlier they believe they know the identity of the suspect.

They say the crime spree started with a carjacking on the North Side of Chicago on Friday. Chicago police say officers were attempting to pull over the suspect Saturday at the time of the fatal crash.

Donovan’s older brother, Derrick Turnage, was in the passenger seat at the time of the crash. He said the tremendous impact resulted in his little brother being thrown from the vehicle. He said he rushed over to his brother, cradled his head and told him to hold on.

Derrick Turnage called his sibling a “special kid.”

“He was just goofy. All the men in our family are goofy,” Derrick said, smiling. “He touched a lot of people.”
