MORGANTOWN, W.Va. -- Morgantown authorities are investigating seven street fires set after the West Virginia-Baylor football game. Police say one fire spread to three parked vehicles and destroyed them. That fire also caused about $1,000 in heat damage to the exterior of a house. The vehicle damage totaled an estimated $35,000. All seven fires occurred late Saturday night and early Sunday morning. West Virginia students and their friends regularly start bonfires to celebrate everything from a major sports victory to the end of a semester. WVU beat Baylor 70-63 on Saturday in its Big 12 debut. WVU has joined police in cracking down on fire-starters. During the last school year, at least 10 students were expelled.
