The city of Detroit is being urged to remove miles of obsolete power lines that could fall from poles and turn deadly.

The recommendation comes from staff at the Michigan Public Service Commission, which oversees utilities.

In September, 12-year-old K'Brianna Griffin was killed when she came in contact with a downed line in a friend's yard. The line was abandoned and inactive, but it was energized and dangerous because it was resting on a live power line.

Detroit says it could cost roughly $36 million and take years to remove 900 miles of overhead wire.

It's another challenge for a city trying to refresh itself, nearly two years after emerging from bankruptcy. City attorney Butch Hollowell declined to say whether Detroit will follow the recommendations.
