NEWARK, N.J. (AP) — The sentencing of a New York man convicted of sex-related crimes involving two New Jersey teenagers was briefly halted Monday after he bit the inside of his mouth and spit blood at one of them.

Once the federal hearing resumed, Clifford Wares eventually was sentenced to life in prison.

Wares, 43, of Warwick, was convicted last month on several counts, including child pornography production and interstate travel to engage in illicit sexual conduct. He didn’t attend all of his trial, saying he feared he couldn’t control himself.

On Monday, the judge also found Wares guilty of obstruction of justice after determining that he sent anonymous letters threatening his victims and their families.

U.S. marshals tackled the shackled Wares when he began spitting at the girl, who was passing between the defense and prosecution tables after completing her victim impact statement. The marshals wrestled Wares to the ground and put a hooded net over his head, then escorted him out of the courtroom to a holding cell.

Prosecutors say Wares met a 14-year-old girl online in June 2011. They say he regularly engaged in sexually explicit communications with her over the next three months and sent her pornographic images, and also told her he was interested in “hanging out” with her.

Wares eventually drove from his home to Passaic County in northern New Jersey, according to the prosecution, where he picked up the teen in his vehicle and the two then engaged in sex acts in a nearby park.
