Three friends from Cecil County were among four people killed and 16 injured in accidents on Maryland roads yesterday.
The fourth death occurred on Interstate 83 in Baltimore County when a car and truck collided.
The Cecil County crash, on Carpenter's Point Road between Perryville and Charlestown, also left three people injured, Maryland State Police said.
Six people - ages 18 to 20 - were riding in a 1992 Ford Explorer that hit a tree after the driver lost control of the SUV just before 6 a.m., police said.
Killed were Lisa R. Taylor, 18, and her sister Johnnie M. Brown, 20, both of the 100 block of Cecil St. in Charlestown, and Thomas W. Emory, 20, of the 200 block of Cecil St.
His brother, Joshua S. Emory, of the same address, was in critical condition late yesterday police said.
Another passenger, Joseph C. Grove, 19, of the 100 block of Cecil Ave. in North East was also in critical condition.
The driver, Raven N. Dorsey, 19, of the 600 block of Carpenters Point Road in Perryville, was in serious condition, police said. The injured were taken to Christiana Hospital in Delaware.
Investigators believe speed was a contributing factor in the accident, said Sgt. Thornnie Rouse, a state police spokesman. No charges have been filed.
A Baltimore woman was killed on Interstate 83 near Ruxton Road about 1:45 p.m., state police said.
Norma S. Mason, 67, of the 3400 block of Dolfield Ave. in Northwest Baltimore was a passenger in a Hyundai Sonata traveling north on the highway.
Police said the driver, Theresa B. Holman, 45, who is Mason's daughter, tried to swerve the Sonata in front of a tractor-trailer, but the truck hit the Sonata, which ended up in the median, police said.
Holman, Holman's daughter Joy A. Woods, 23, and Woods' 5-month-old son, Joshua - all of the same address on Dolfield Avenue - were taken to Sinai Hospital. Hospital staff would not release information on their conditions.
The driver of the Mack truck from Akron, Pa. was not injured, said Maj. Greg Shipley, a state police spokesman. The accident closed the northbound lanes of the expressway for an hour.
Earlier, state police shut down the inner loop of the Baltimore Beltway near Providence Road for nearly an hour, causing a six-mile backup, police said.
The inner loop was closed about 11:15 a.m. after a driver heading west on the outer loop lost control of her 1991 Toyota 4-Runner, police said. The SUV hit the jersey wall and flipped over into the inner loop, where it was hit by a tractor-trailer truck, said Ragina C. Averella, a state police spokeswoman.
The driver, Cari A. Crabtree, 16, of the 800 block of Cedar Lane in Bel Air, was treated at Johns Hopkins Hospital and released. Her 51-year-old father and 12-year-old brother were being held last night for observation at Hopkins, Averella said.
In Anne Arundel County, seven people, including three children, were injured when three cars collided on Telegraph Road in a residential development in Odenton, police said.
The children were flown to Johns Hopkins Hospital, and two adults were flown to Maryland Shock Trauma Center, said Anne Arundel County Fire Department Capt. Lee Cornwell. Two adults with less serious injuries were taken to Johns Hopkins and North Arundel hospitals.
Authorities would not release the names of the victims or their conditions yesterday.
