Manslaughter conviction: A Silver Spring man was convicted yesterday of killing a cyclist when he lost control of his car while speeding on Sligo Creek Parkway.

Scott A. Davis, 25, faces up to 10 years in prison for the manslaughter conviction in the Jan. 10 death of Walter Penney, 48, of Takoma Park.

Prosecutors told a Montgomery County Circuit Court jury that Davis's car, traveling nearly 60 mph in a 25 mph zone, crossed the double center line on the parkway near Dallas Avenue and struck Penney.

Residents say that speeding has been a constant problem on the parkway. The County Council approved $150,000 in May to increase enforcement and add measures to slow traffic.

Child abuse, assault charges: Frederick police charged a Gaithersburg man yesterday with assault and child abuse after his 8-month-old son's skull was fractured.

Curtis E. Faulkner, 20, is charged with child abuse and first- and second-degree assault, said Lt. Thomas V. Chase, head of criminal investigations for the Frederick Police Department.

Chase said the infant was injured Monday night while Faulkner was watching him in the Frederick home of the baby's mother, Britney Dorsey, 19. The baby was admitted to the hospital the next day, Chase said, and was in critical condition yesterday at Children's Hospital.
