Lawyers are investigating reports that Nicole Brown Simpson and Ronald Goldman met with a therapist days before they were killed and that O.J. Simpson had threatened Goldman.

It wasn't clear whether Nicole Simpson and Goldman met together with the therapist, Jennifer Ameli, or what impact the reported meeting might have on the wrongful-death lawsuit against Simpson.Adding to the mystery are police reports showing that files were stolen from the therapist's office and that she was followed and threatened.

Lawyer Daniel M. Petrocelli plans to ask Ameli about a published report that the victims told Ameli that Simpson had threatened Goldman just before the killings, Goldman's father said.

The National Enquirer said its report this week was based on an anonymous "insider who knows what Ron and Nicole told the therapist." The Enquirer also said Goldman was romantically involved with Nicole Simpson - an assertion that his father, Fred Goldman, flatly denied.

"We know that wasn't correct," he told reporters Thursday outside Petrocelli's office where Simpson was giving a deposition for the lawsuit.

Michael Brewer, who represents Goldman's mother, Sharon Rufo, said lawyers for the victims' families had seen records from Ameli's office indicating Nicole Simpson met with the therapist on June 9, 1994. The records also show Nicole Simpson was concerned about her ex-husband. Brewer did not elaborate.

A message left for Ameli was not immediately returned.

Brewer said Thursday's questioning of Simpson dealt primarily with the issue of domestic violence. Simpson was agitated by some of the questions but there were no outbursts, he said.

Simpson was acquitted in the June 12, 1994, slayings of Nicole Simpson and Goldman. The victims' families filed the lawsuit against Simpson, seeking unspecified damages.

Meantime, police reports reviewed by The Associated Press show that on Sept. 15, 1994, Ameli reported a burglary at her office, saying files, a calendar book and other papers were taken. The police report said there was no sign of forced entry.

There was no mention in the police report that the material pertained to Goldman or Nicole Simpson, but the Enquirer reported that the files did relate to them.

Ameli filed a second police report a short time later, also reviewed by the AP, saying someone followed her to her office and threatened her from behind. In the report, she quoted the person as saying, "Don't turn around. Keep walking. You've been talking about Goldman. You better keep your mouth shut if you know what's good for you."

Sources from both the defense and prosecution in Simpson's trial told the AP that Ameli was well known to both sides, yet attorneys decided not to use her.
