A 20-year-old District man was found guilty of robbing an elderly woman of her high-end automobile and leading police on a high-speed chase through crowded residential streets in Southeast D.C., U.S. Attorneys announced.

Arthur Vincent Daniels was convicted of 14 charges, including armed carjacking of a senior citizen, assault on a police officer while armed, destruction of property and other offenses.

On the morning of Feb. 9, authorities say Daniels pointed a loaded pistol at an 84-year-old, who was alone near her Mercedes-Benz on the 200 block of G Street SW at about 8:20 a.m. Daniels was able to elude police at the city border as he drove into Prince George's County, according to attorneys.

Daniels committed another crime in Landover that morning -- he stole a woman's purse at a gas station, according to police -- before driving back into the District at approximately 9 a.m., authorities said.

That's when Daniels was spotted by officers and began a wild and threatening 45-minute police chase in neighborhoods in Southeast D.C., attorneys said.

Daniels reached speeds of up to 100 mph on busy city streets, ran red lights and repeatedly drove on the wrong side of the road while trying to escape police cruisers on his tail, according to authorities.

Twice he aimed the Mercedes directly at police vehicles to force them off the road. One cruiser was totaled in the chase, according to authorities.

One officer was injured in the pursuit, which involved law enforcement from the D.C. police Department, Prince George's County police, Capitol Police and U.S. Park Police.

Police caught Daniels after he bailed out of the stolen car and ran into his residence. Authorities found Daniels pretending to sleep in his mother's bed, according to attorneys. A search of the home turned up the pistol used in the carjacking and clothes that Daniels wore that morning. Police found the purse stolen at a Landover gas station inside the Mercedes, which had sustained $10,000 worth of damage.

Daniels' older brother, Arthur Lee Daniels, 22, was acquitted of charges of unauthorized use of a vehicle and receiving stolen property.

The conviction for armed carjacking alone carries up to a 60-year sentence -- an enhancement based on the victim's age, which qualifies her as a senior citizen.

Daniels is scheduled to be sentenced in D.C. Superior Court on Feb. 21.
