Key evidence against Colts Neck youth tennis instructor Terry Kuo, on trial on charges of sexually assaulting an underaged student, are photographs found on his electronic devices depicting a man's hand on a young girl's genitalia.

So, when a prosecutor on Thursday made a motion to have Kuo's hands photographed in an effort to show the jury that the hand in the photographs is Kuo's, the defendant repeatedly interrupted the proceeding, leading to his removal from the courtroom during the second day of his trial.

Kuo, 32, is accused of having a sexual relationship with a female tennis student between August 2016 and November 2017, when the girl was 12 and 13.

He is charged with kidnapping, aggravated sexual assault, sexual assault, aggravated criminal sexual contact, criminal sexual contact, causing or permitting a child to engage in pornography, manufacturing child pornography, possessing child pornography, obscenity, endangering the welfare of a child and conspiracy to tamper with evidence.

Just before the trial's lunch break, Ryan Lavender, assistant Monmouth County prosecutor, made a motion outside the presence of the jury to compel Kuo to either show his hands to the jury or have his hands photographed to present to the panel.

As Superior Court Judge Jill Grace O'Malley was granting the prosecutor's request to photograph the defendant's hands, Kuo interjected.

"I object to having any photos of my hands taken at this time," Kuo said.

"I'm being forced to do something once again that I don't want to do," he said.

O'Malley said that another judge in 2019 granted the same motion, but because Kuo burned his hands during an incident at the Monmouth County Jail shortly afterward, that "prevented the state from obtaining the photographs in their truest and purest forms."

As O'Malley was issuing her ruling, Kuo interrupted again.

"I have to use the bathroom," he said.

Kuo caused a mistrial in the case earlier this year when he urinated in the courtroom in front of prospective jurors as jury selection was underway. Superior Court Judge Joseph W. Oxley, who was presiding over the case then, stated he believed the act was intentional.

O'Malley, at a pretrial conference last week, called that act a deliberate stalling tactic.

On Thursday, Kuo already had been given bathroom breaks when he interrupted the judge to request another one.

"I've noticed, conveniently you never have to use the bathroom when your attorney is questioning witnesses, but whenever the court is ruling or the state is questioning witnesses, you have to use it with urgency," O'Malley told him. "You will wait until I'm done."

O'Malley continued with her ruling, but was interrupted again, this time by Lavender, who alerted the judge that Kuo had his hands beneath the defense table, rubbing them against the table.

The judge ordered sheriff's officers to remove Kuo from the courtroom.

"The defendant was attempting to manipulate his hands, the very object that the state is here to photograph," O'Malley said.

"Your honor, I had ink on my hands," Kuo said as he was being led out of the courtroom.

With the defendant removed, O'Malley continued.

After a previous judge ordered that Kuo's hands be photographed in 2019, "the defendant had a convenient burn accident at the county jail, and for that reason, the state could not get the photographs that the court granted," O'Malley said.

"The court finds this to be a deliberate activity on behalf of the defendant, another stall or dilatory tactic on behalf of the defendant," the judge said.

"He's putting on a show throughout these entire proceedings," O'Malley said of the defendant.

Earlier in the morning, while a detective was being cross-examined by Kuo's attorney about photos and other evidence found on Kuo's electronic devices, Kuo placed a stack of papers on the defense table and placed his head down, sideways, on the papers for much of the cross-examination.
