MINEOLA - The principal of JFK High School took the stand for the second day today as the trial of a former top Nassau County Police Department official continues.

William Flanagan, once third in charge of the entire department, is accused of trying to let the son of a police donor off the hook in exchange for donations to the department and other favors. Lorraine Poppe, principal of JFK High for 18 years, today defended emails she had written about the donor's son, Zachary Parker.

Parker was accused back in 2009 of stealing more than $10,000 worth of electronics from the high school.

In one email submitted in court today, Poppe told a Nassau detective, "I have to speak with the superintendent about whether we want Zach arrested or whether we are going to give him a long-term suspension...if everything is returned."

In another email hours later, Poppe wrote that she'd asked police to "put everything on hold."

Poppe defended her words today, saying there was much more to the discussion than just the emails. She insists that she always wanted Parker arrested, and says she never retracted that statement. Poppe is expected to return to the stand tomorrow.

Flanagan has been charged with conspiracy and official misconduct and faces up to four years in prison if convicted. His lawyer maintains that his only involvement in the case was to see that the stolen property was properly returned to the school.
