BOSTON (WHDH) -- New questions are being raised about disgraced state chemist Annie Dookhan and her relationships with local prosecutors.

State police said the Department of Public Health has turned over all of Dookhan’s work emails, reportedly including some emails showing Dookhan communicating in an unusually person and friendly way with at least one Norfolk County prosecutor.

The prosecutor turned in his resignation on Wednesday.

District Attorney Michael Morrissey released the following statement:

“After discussions with his supervisors, Assistant District Attorney George Papachristos has offered his resignation and District Attorney Michael Morrissey has agreed to accept it. George Papachristos communicated that he does not wish to be a further distraction from the central issue of the criminal conduct that has been alleged and the complete breakdown of supervision that allowed it to continue.”

The emails have some asking whether Dookhan was pushing beyond the bounds of a professional relationship with the prosecutors.

Judges have already tossed out some drug convictions because of questions about Dookhan’s handling of drug samples. The ACLU is reportedly now asking that the courts also throw out any cases where Dookhan inappropriately communicated with prosecutors or police.

Governor Deval Patrick only said the office he set up to look at all the cases might be affected by the state drug lab scandal.

“I’ve had my own questions -- many people have -- about why the chemist would do this. I don’t know yet if these emails help explain that. My job right now…is to make sure justice is done for all those people whose cases were affected,” said Patrick.

Dookhan is accused of falsifying results at the now-closed state drug testing facility. Officials said Dookhan may have compromised 34,000 cases.
