The lighted "M" overlooking Montana Tech on Butte's north side will be dark for a while after someone shot out all 120 light bulbs over the weekend.

Montana Tech spokeswoman Amanda Badovinac says .22-caliber bullet casings were found on the ground at the base of the "M," which was constructed by Tech students in 1910.

Art Anderson is director of the campus' physical plant. He says he suspected the lights were out Saturday night because of a malfunction that has occurred in the past. However, crews on Monday discovered the bulbs had been shot out.

The college filed a police report Tuesday.

Anderson estimates it will cost about $2,400 to replace all 120 50-watt bulbs and the 120 globe covers that protect the bulbs. It could be more than a week before the replacements arrive.
