Law enforcement agencies all across the country are on the look out for 14-year-old Karley Bletz of Punxsutawney. 

Police said she was last seen on August 28. 

Bletz's family members told 6 News they believe she ran away with registered sex offender, Donald Guthrie. 

On Monday, 6 News sat down with Karley's mother, Jaimee. 

Jaimee Bletz said that Karley had been in contact with Guthrie for some time now.  She said that she has been trying to keep the two away from each other. 

Guthrie became a registered sex offender in 2003. 

According to the Megan's Law website, Guthrie is a 10-year offender.  It said his primary offense was indecent assault. 

Jamiee Bletz said that when she received one phone bill she noticed Guthrie had text her daughter over 2,000 times. 

She said he is from Jersey Shore, where the Bletz family also has relatives. 

Jaimee Bletz said initially, Guthrie told Karley that he was her father. 

Her mother denied that claim. 

Jaimee Bletz said she took her daughter's cellphone away, but somehow she kept catching her with more phones.

Jaimee Bletz believes that Guthrie has something to do with that. 

Earlier this month Jamiee Bletz put her daughter in temporary foster care.  She said she wanted her daughter to be somewhere safe until Guthrie had his court date.

According to web dockets charges were filed earlier this year against Guthrie for indecent assault and child pornography. 

Jaimee Bletz said that she put her daughter with a foster family in mid-August.  She believed everything was going OK until she got a call from the family the morning of Aug. 29. 

Jaimee Bletz was told that Karley cut the screen out of the window in the middle of the night and ran away. 

Friends of Karley told Jaimee Bletz that Karley had previously mentioned that she had planned on running away with Guthrie. 

Jaimee Bletz believes her daughter is with Guthrie. 

Friends told Karley's mom that she and Guthrie had been having sex on multiple occasions.

According to web dockets Guthrie was scheduled to appear in court on Aug. 31.

He never showed. 

Police in Jersey Shore told 6 News that they are on the look out for Guthrie.
