An FBI agent was charged with 64 criminal offenses today related to allegations that he tampered with “substantial quantities” of drug evidence for personal use.

In September, Matthew Lowry was found unconscious a vehicle that was later found to have drugs, kicking off a major misconduct investigation.

The case forced prosecutors to drop charges against 28 defendants in three drug cases that Lowry was involved with. They also notified more than 150 other defendants that Lowry had worked on their cases in some way.

Lowry, 33, had been with the FBI since 2003. No other agents were found to be involved.

If convicted, Lowry faces more than seven years in prison, three years of supervised release, a fine of up to $16 million, and a $6,400 special assessment.

In a statement, Lowry’s lawyer said that his client will plead guilty to all of the charges and “recognizes the importance of taking full responsibility for each of his acts.” He adds that Lowry is “devastated by the consequences of his conduct” and attended a three month rehabilitation program in the fall.

A sampling of the things that Lowry is accused of:

“The defendant participated in an undercover, controlled purchase of heroin from a target, and in lieu of turning the heroin into evidence and documenting its seizure, the defendant allegedly ingested the heroin and never turned it into evidence.”

“In several instances, it is alleged that the defendant went to the WFO’s Evidence Control Center (“ECC”) and removed seized heroin from evidence, writing on a chain of custody record a false explanation for his taking of the evidence.”

“Before returning the heroin to the ECC or bringing it to a laboratory for testing, the defendant allegedly added to the heroin a measured amount of a cutting agent, either the supplement Creatine or the laxative Purelax, in order to account for the weight discrepancy resulting from his illegal usage”
