who perhaps doesn't like malls -- drove a backhoe through his half-completed shopping center in the Seven Corners area of Fairfax County and caused an estimated $150,000 in damage.

"Somebody went berserk with a backhoe and knocked through a brick wall," said Cavallo, project manager of the Willston Centre II.

Then, Cavallo said, the person drove through all the partitions and hit a steel column about eight times. "He really worked on that one," Cavallo said. "Bathrooms and everything else, too."

In the middle of driving through another wall, he said, the driver "ran out of gas."

Cavallo said workers discovered the "unbelievable" work site early yesterday morning. Fairfax County police said the incident occurred between 9 p.m. Monday and 6:30 a.m. yesterday.

Police spokeswoman Carol Kitzerow said pipes, cinder block walls and the internal structure of the building, at 6100 Arlington Blvd., were damaged.

Cavallo, who said a security system was installed yesterday, speculated that the culprit had to know how to operate the machine. If the person had knocked down the steel column with the backhoe, he could have been crushed, according to Cavallo.

"Thank God he didn't have a bulldozer," he said. CAPTION: Picture, Blackhoe was found, out of gas, at this spot after doing an estimated $150,000 damage to half-finished mall in Fairfax. By James K.W. Atherton -- The Washington Post
