Saying he hoped Bobby Pringle "would have nightmares for the rest of his life," a Prince George's County judge sentenced him yesterday to more than 64 years in prison for beating and stabbing his disabled mother more than 70 times.

Judge William D. Missouri sentenced Pringle to life imprisonment for the first-degree murder of Dorothy Mae Pringle, whom he killed Aug. 21 on her 57th birthday while he was high on alcohol and drugs.

A life sentence in Maryland carries a mandatory 60-year penalty.

"I've never seen a body as mutilated as the one of your mother," Missouri said, adding that it took him four days to shake the image of the autopsy photographs of Dorothy Pringle's body presented as evidence during last month's trial. "Your mother is the person who carried you for nine months, gave you life, love . . . . How could someone do that to their mother?"

Pringle, 30, also received a concurrent sentence for second-degree murder, and consecutive three-year and 18-month sentences for carrying a deadly weapon with intent to injure and for stealing a television and radio from his mother's Capitol Heights home the evening of the murder.

Pringle told Missouri it didn't matter what sentence the judge imposed, "because I lost my mother." Dorothy Pringle has been described by family members as a devout Baptist who raised four girls and three boys, of which Bobby Pringle was the youngest.

Pringle will be eligible for parole in 15 years, according to prosecutor Andrew Murray.

During his trial, Pringle said he was so high on alcohol and drugs that he did not remember anything that happened after he went to his mother's apartment in the Walker Mills Garden complex, where he occasionally stayed.

Before going home that night, he cashed his paycheck, went to an acquaintance's home and began drinking heavily, Pringle testified. On his way back to his mother's apartment, he stopped twice at a "drug strip" and bought crack cocaine and PCP-laced marijuana, he said. Pringle mixed the drugs to form what is known on the street as "love boat."

Pringle told jurors he recalled arriving at his mother's apartment, waking the next morning and finding her body. The hours in between, however, were a blank, Pringle said.

Defense attorney Maureen Lamasney used Pringle's drug use and subsequent mental condition that night as a defense, saying he was not clear-headed enough to form rational intent to kill his mother.

But Murray argued that although Pringle was high, he was coherent enough to understand what he was doing.
