CONCORD – The criminal charges against former St. Paul School teacher David Pook are back on after Merrimack County Superior Court Judge Brian Tucker issued an order reinstating them.

The four charges, two counts of witness tampering and two counts of perjury, were automatically dismissed last week in the Concord court when the New Hampshire Attorney General’s Office failed to bring the case to a grand jury for possible indictment within the legal timeframe. Most criminal cases stipulate a 60-day limit.

However, Assistant Attorney General Jane Young said Monday the charges were reinstated Friday after the state requested and was granted additional time to bring indictments. Young was not available for comment on Friday.

The records reviewed by The Telegraph show the charges were dismissed as of 1:58 p.m. on Friday. The official case summary was not updated until after 1:30 p.m. on Monday, this time indicating the charges were reinstated.

Defense attorney Mark Sisti, who said Friday there were no pending criminal against his client, said late Monday he had yet to receive any order from the court stating otherwise.

Pook, 47, of Warner, was charged at the end of February for his alleged actions surrounding the grand jury convened to investigate sexual assault problems at St. Paul School in Concord. Pook allegedly had a sexual relationship with one of his St. Paul students before he was fired in 2008. Last year, Pook allegedly tried to get the young women with whom he allegedly had a sexual relationship to lie before the grand jury.

The state has been investigating sexual assaults at St. Paul in the wake of the Owen Labrie scandal. Labrie was found guilty in August 2015 of luring an underage student into a sexual encounter while he was an upperclassman. He was convicted on sexual assault and child endangerment counts. The case sparked outrage over the allegedly widespread practice of upperclassmen at the school targeting freshmen for sex.

The Episcopal school is now the subject to two lawsuits, one in which a recent female student alleges she was sexually assaulted and harassed by other students, and another lawsuit filed by two former students from the 1960s and 1970s alleging sexual misconduct by faculty.
