Tekashi 6ix9ine will get his sentence on December 18, a week from today.

There is some expectation he will be released with time served (about a year) because he rolled on his former Nine Trey brothers and testified for the government in open court.

In the wake of the sentencing, 6ix9ine has penned a letter to Judge Paul Engelmayer. In it, he renounces his gang ties and apologizes for his crimes. He also gives insight into why it took him less than a day to decide he would snitch, rather than face up t0 47 years on racketeering and weapons charges.

"Prior to my arrest, I was kidnapped by members of the gang, became aware of the fact the mother of my child was having sexual relations with one of my co-defendants and that they were stealing hundreds of thousands of dollars from me," 6ix9ine wrote. "I had a feeling of relief when I was arrested by the Government because I felt stuck, like the gang had control of my life and I would never be able to escape their grip. I needed to do something before it was too late."

If 6ix9ne is released next week he is expected to turn down witness protection and resume his music career.
