police interviewed Dookhan at her home in Franklin, where she admitted to altering and faking test results in order to cover up her frequent "dry labbing," or visually identifying samples without actually testing them. She even went as far as to add cocaine to samples in which no cocaine was present.[6] She said she had been dry-labbing for as long as three years. At one point, she broke down, saying, "I messed up, I messed up bad. I don't want the lab to get in trouble."

Dookhan was sentenced to three to five years imprisonment and two years probation by Judge Carol S. Ball in Suffolk Superior Court, after pleading guilty to crimes relating to falsifying drug tests.[1][13][14] This was greater than the one year sentence her defense requested but less than the five to seven year sentence requested by the prosecution.[13][14] However, Ball said that upward departure was merited due to the ramifications of Dookhan's misconduct. Ball wrote, "Innocent persons were incarcerated, guilty persons have been released to further endanger the public, millions and millions of public dollars are being expended to deal with the chaos Ms. Dookhan created, and the integrity of the criminal justice system has been shaken to the core."

The vast majority of these convictions have not been overturned.
