When Deandre Robinson demanded a woman’s car keys as she pulled a stroller from her Toyota minivan one snowy evening in the District in February 2010, the woman cried out: Her 4-year-old daughter, physically disabled, was inside, strapped in a car seat.

But Robinson pushed her aside, according to court documents, driving off as she chased him, screaming and crying. A few miles away, he pulled into a parking lot and shoved the girl, car seat and all, under a parked car.

The girl was later found unharmed after a witness spotted her shoeless foot, court documents said.

Robinson, 20, of Landover, was sentenced Friday to seven years in prison after pleading guilty in October to one count of carjacking.

Robinson apologized to the girl’s mother, who wiped away tears as she sat in the back of the courtroom.

“I wish I could take everything back that I did,” Robinson said.

After his arrest, Robinson repeatedly told authorities that he was drunk when he stole the vehicle in the parking garage at Children’s National Medical Center and did not know the girl was in the minivan. Kevin McCants, Robinson’s attorney, argued for a three-year sentence.

But Assistant U.S. Attorney Maia Miller argued before D.C. Superior Court Judge Robert E. Morin that intoxication did not explain the carjacking — or abandoning the child.

“He left her there for dead. He ignored her cries,” Miller said of Robinson.

Abandoning the child on a snowy and cold night showed Robinson had “really bad instincts,” said Morin, who gave him the maximum sentence allowed under his plea agreement.

Robinson was also sentenced to three years of probation. If not for the agreement, Morin said that he might have given Robinson a harsher sentence.
