A Springfield teen-ager was seriously injured Friday night after being struck and dragged by a pickup truck during a high school graduation party, according to Fairfax County police.

At least two Annandale youths were also slightly injured when the pickup truck jumped a curb, drove across a lawn and slammed into a crowd of teen-agers gathered on the lawn to celebrate the senior class' June graduation from Annandale High School.

Police yesterday afternoon arrested JohnRodgers, 19, of 7717 Bristow Dr., Annandale, and charged him with malicious wounding.

Witnesses said the incident stemmed from an earlier argument between a high school senior and a senior girl at Annandale. After the argument, one witness said the girl threatened to get her boyfriend to settle the score.

Mark Scott of Springfield, who suffered severe internal injuries, was listed yesterday in serious but stable condition after emergency surgery at Fairfax Hospital.

Witnesses said Scott was run over by the wheels of the truck, and showed tire marks across his back.

At least two other youths were injured but did not require hospitalization.

The three youths were among about 50 teen-agers attending a graduation party at the home of 18-year-old Robert Morris on Queensberry Lane in Springfield.

Several of the teen-agers at the scene said the party had been going on for about an hour when the pickup truck, carrying two youths and a girl, appeared and began driving around the block.

Mrs. Edward Wingo, who lives in the house across the street from the party, said that she saw the crowd crossing the street, and went to her front window to watch. Suddenly, she said, "a big, four-wheel truck" came downhill toward her house, jumped the curb, rolled across her front yard and slammed into the crowd standing there. The truck then drove away.
