North Sewickley police say 23-year-old Joseph Russell and 24-year-old April Cater cut down the wires on August 9, four days before their wedding.
Russell says he was desperate for money because he'd just lost his job and lost a $1,000 deposit after his reception hall abruptly closed down.
Sgt. Jeff Bezce says the couple clearly expected to get more money than they got from the scrap where they sold the copper.
Russell tells WPXI-TV he will pay for the damages. Utility officials say it will cost about $400 to repair of the 18 poles that were damaged.
