The parent whose confrontation with a Kaiser High School football coach ended the team’s season early is asking a state judge to dismiss the criminal charges against him.

An Oahu grand jury indicted Gregory Tartamella in November for assault and terroristic threatening, both felonies, and two counts of petty misdemeanor harassment. The charges stem from a Sept. 18 confrontation at the school involving Tartamella, 41, his wife, Kaiser teacher and head football coach Arnold Martinez, school security guard Nick Hironaka, Vice Principal Kevin Dias and others.

Much of the confrontation was recorded on cellphone video.

Martinez told the grand jury that Tartamella hit him on the arm, knocking the items he was carrying to the ground, called him a “fake Christian” and challenged him to fight by threatening to “baptize” him.

Hironaka testified that when he intervened, Tartamella poked him in the head with his finger and threatened to blow his brains out.

Dias told the grand jury that as he and others were escorting Tartamella and his wife to the school’s parking lot, Tartamella threatened him by telling him, “I’ll f—- you up.”

Tartamella’s lawyer Eric Seitz says the video does not show Tartamella hitting Martinez or show Martinez reacting to being hit, does not show Hironaka or Dias showing any sign of fear or alarm and does not show Tartamella taking a fighting stance. He says had the state played the video for the grand jury as it should have, the grand jurors would not have returned an indictment against Tartamella.

Deputy Prosecutor Catherine Lowenberg says the video supports the testimonies of Martinez, Hironaka and Dias, which supports the indictment. She is also asking Tartamella to declare whether he plans to use a mental defense.

Honolulu police arrested Tartamella at his Kailua home in March on a charge of misdemeanor abuse of a family or household member. He was later charged with petty misdemeanor harassment.

His wife told police Tartamella threw an object and hit her teenage son in the face during an “episode of some kind of mental distress.” She said her husband had been taking antipsychotic medication and seeing a psychologist because he needs mental help.

The day after the September confrontation, Kaiser Principal Justin Mew announced that the school was canceling the rest of the football season and forfeiting the rest of its games. Martinez stepped down as head coach 11 days later.
