Police in Cleveland are asking for the public's help in finding teen Madison Rich. She has been missing for over 40 days.

The search began the night of August 14. Maddie was at home, but sometime in the early morning hours of August 15, she left. Maddie had left home for a few days in the past, but she had always maintained contact with friends via social media.

At the beginning of this incident, when her mother found Madison gone on the morning of August 15, she was worried but discovered her daughter was still communicating on social media.

For the next few days, Maddie communicated with friends via phone and Snapchat. Her family was able to track her on the 15th, 16th, and 17th. Maddie's mom became increasingly concerned because Maddie has medical issues that require medication, but her medication remains at home.

Every day since Maddie has gone missing, her mom Tracy has been posting to social media about her daughter and, thanks to a local company, has placed two large signs in her front yard. Each sign displays Madison's picture and information.

Lakewood police say when Madison Rich left her westside home in Lakewood, she initially stayed at a friend's home in Cleveland and communicated with other individuals via phone and Snapchat. On August 18th, Maddie left the friend's home, and law enforcement picked up her phone's GPS location in Warrensville Heights, Ohio.

Police tried tracking her phone after August 18 and determined the phone has been rendered inoperable, has been turned off, or the battery has died. Regardless of the reason, the phone has not registered with any cell tower since August 18.

Police have sent out a BOLO for 17-year-old Madison Rich. "Maddie" is 5 feet, 7 inches tall, weighs 110 pounds, and has blonde hair and blue eyes. She has a spider web tattoo on her right arm and a mole on the left side of her cheek.

Police are asking the public for help in finding Maddie, hoping to bring her home before her 18th birthday this month.
