DEDHAM, Mass. (AP) _ John C. Salvi III talked so much about conspiracies against Roman Catholics that his uncle stopped talking to him altogether, the uncle testified today.

Dennis Trudel let his sister's only son move into an upstairs apartment in his Ipswich home in the spring of 1993. Salvi's family had moved to Florida, and Salvi wanted to return to Massachusetts.

``I would tell him what he was saying was so crazy, there was no point to discussing'' it, Trudel, 50, told jurors at Salvi's murder trial. He said Salvi was insisting that Freemasons, the Mafia and the Ku Klux Klan were persecuting Catholics.

Defense lawyers are using an insanity defense for Salvi, acknowledging he killed two receptionists and wounded five other people in back-to-back rifle attacks on two abortion clinics in suburban Boston.

One day, Trudel recalled, Salvi kicked in two doors and confronted his frightened uncle, saying: ```Better watch out, little man. Better get your gun. They're going to get you.''

Under cross-examination from the prosecution, the defense witness admitted that he didn't tell the police about the incident. It was just a family thing, an argument we had,'' Trudel said. ``It wasn't a criminal thing. He got mad at me.''

On Monday, a friend testified that Salvi told him he heard voices sometimes when he read the Bible, and wondered whether others heard them too.

``He said, `Did you ever feel one minute you're normal and then the next something starts talking to you?''' said Christine Lockshire, who went out with Salvi three times between September 1993 and August 1994 after her mother introduced them.

``I asked him what he meant,'' Lockshire testified Monday. ``All he said was that he heard voices. ... He said they just popped out of nowhere.''

On cross-examination Monday, a psychiatrist acknowledged that Salvi revealed some of his paranoid delusions only after learning that his lawyers planned an insanity defense.

Dr. Phillip Resnick, a defense witness who diagnosed Salvi as a paranoid schizophrenic, said Salvi did not bring up certain topics during two interviews after the December 1994 attacks.

But on the day before he trial started, Salvi talked about a conspiracy to force birth control on Roman Catholics and said it was justifiable to kill people who wanted to interfere with a currency system just for Catholics, Resnick testified.

``So now ... he tells you it's justifiable,'' prosecutor John Kivlan said, ``and he had never made that statement to you before, until the day before the trial?''

``Yes,'' Resnick replied.

Lockshire's mother, Cindy Lockshire, testified for the defense that Salvi once told her, ``He had evil on one side and good on the other side, like they were standing on his shoulders.''

She didn't take the statement seriously at the time, thinking he was referring to a TV show, she testified.

Mrs. Lockshire also said Salvi told her he slept with the Bible under his pillow because it made him feel safe from the evil outside his door.

Both Lockshires described Salvi as shy, polite and kind.
