A defense lawyer says a teenager accused of fatally stabbing a New York City radio reporter during a sexual encounter was defending himself.

John Katehis (kah-TEH'-hihs) is charged with killing 47-year-old George Weber in the victim's Brooklyn apartment in March 2009.

The defense said at a pretrial hearing Tuesday that Weber had inflicted cuts on Katehis' hands before Weber was killed.

Authorities say Katehis had answered Weber's Craigslist ad offering to pay for sex.

Weber worked 12 years as an on-air reporter at WABC in New York. He also had worked at stations in California, Colorado and Pennsylvania.

Discussion at the hearing also focused on what evidence may be admitted at the murder trial.
