ST. LOUIS (KMOX) – Following the shooting death of former St. Louis University volleyball player Megan Boken during a cellphone robbery in August, the St. Louis Board of Aldermen went to work drafting a bill that makes it tougher to re-sell stolen cell phones to second-hand dealers.

Mayor Francis Slay announced the signing of that bill into law on Friday.

Slay says it requires second-hand dealers to record the phone’s identity number and collect other information from the seller — even the person’s thumbprints, “We took the lead here. I’m not sure there’s any other city in America doing this. One thing we know is like a lot of cities in America, while overall crime is going down, cell phone crimes are going up.”

The city’s new police chief, Sam Dotson, believes the law will work, “When a cell phone is taken, if there’s no place to sell it, there’s no reason to take it, no reason to commit the crime.”
