WASHINGTON (AP) _ Would-be presidential assassin John W. Hinckley Jr. will continue seeking permission for unsupervised visits with his parents even though a psychiatric facility where he has been confined since 1982 has withdrawn support for the trips, his attorney said Thursday.

At a hastily scheduled hearing, Senior U.S. District Judge June L. Green canceled a July 17 hearing on the issue of unsupervised visits a day after St. Elizabeths Hospital withdrew its own recommendation that Hinckley be allowed weekly trips to see his parents without a hospital escort.

Hinckley's attorney, Barry Levine, said they needed time to consult with Hinckley's doctors before making a new petition to the court.

The hospital's announcement followed a hearing where prosecutors said Hinckley, who shot President Reagan in 1981, has a ``continued interest in violently themed books and music.''

Levine said the hospital wasn't making a medical decision, but was embarrassed because it knew Hinckley read books, yet failed to ask about their content.

``Members of the treatment team did not know the hospital had withdrawn this petition,'' Levine said.

Hospital spokeswoman Phyllis Blair said withdrawing their recommendation was not unusual.

``Any time there is information that was unavailable or was unknown to us originally, then we may make a request to reconsider,'' she said.

In April the hospital said Hinckley had sufficiently recovered from his mental illness to justify brief unescorted releases.

During the past year, he has been able to go on supervised trips with other patients to stores and restaurants. The Secret Service and U.S. attorney's office are notified whenever a trip is planned.

Levine maintains that open visits are a necessary step in Hinckley's recovery, and that his illness has been in remission.

Hinckley, 45, shot Reagan and three other people in March 1981. He said he did it to impress actress Jodie Foster. He was found innocent by reason of insanity.
