A 12-year-old Haymarket girl and a Manassas man were killed Saturday night when a sport-utility vehicle driven by the girl's mother collided with an approaching vehicle whose driver was later charged with drunken driving, Prince William County police said.

Rachel Kaplan, a seventh-grader at Bull Run Middle School in Gainesville, was airlifted to Inova Fairfax Hospital, where she died shortly after the crash, police said. Alejandro Garcia Martinez, 26, a passenger in the other car, died at the scene, police said.

Police gave this account of the accident:

Robin Kaplan, 43, was driving east about 9:15 p.m. on a rolling, rural section of Logmill Road with Rachel in the front passenger seat. At the crest of a hill, she tried to turn her Toyota RAV4 SUV left onto Parnell Court, the entrance to the Haymarket subdivision where the Kaplans had recently moved. As Kaplan turned, a Volkswagen Jetta heading west on Logmill Road struck the Toyota's right side.

Ricardo Batista, 20, the man driving the Jetta, was flown by helicopter to Inova Fairfax, where he was treated and released. Police charged Batista with drunken driving. He is being held on $5,000 bond, said Sgt. Kim Chinn, a spokeswoman for Prince William County police.

Chinn said that police are continuing to investigate the crash but that speed was not a factor. All four passengers were wearing seat belts, she said.

Robin Kaplan was transported by ground to Inova Fairfax, said Capt. Tim Taylor, a spokesman for the Prince William County Fire and Rescue Department.

Trevor McNeal, who lives down the street from the Kaplans on Parnell Court, said it is difficult to see oncoming traffic at the hilltop intersection of Logmill Road and Parnell Court, which, he said, had been the site of at least three other traffic accidents since March. He said he and other neighbors were planning to write a letter to the county complaining about the entrance to the subdivision, saying it should have been located along a flat stretch of Logmill Road nearby.

"This never should have happened," he said. "It all could have been avoided."

Batista and Martinez both lived in the 10800 block of Gambril Drive in Manassas, Chinn said. Family members could not be reached yesterday.

Rachel was new to Bull Run Middle School this year but had already made a name for herself as a "good kid," said William G. Bixby, the school's principal.

"She was well liked and popular," Bixby said. "It's a tragic loss, and our school community will pull together to try to support her family and friends."

McNeal said the Kaplan family had moved from Clifton to Haymarket during the past few weeks. The girl's father, Glenn Kaplan, 43, is an employee of the Fairfax County Fire and Rescue Department.

Rachel Kaplan was a tall, slender dancer who looked older than her age, said McNeal, 33.

He said Robin and Rachel Kaplan were coming home from a party when the collision occurred. McNeal said Robin Kaplan told him after the crash that Rachel "was so excited that we had two kids and there were a bunch of kids in the neighborhood. She was fixing to put out a flier that she wanted to baby-sit."
