The defense rested its case Thursday in the trial of Clarence Leake, charged with invading the Washington LDS Temple in October 1986.

Earlier, Leake's father, Donald Leake, interrupted his son's trial with noisy objections to testimony about his conduct as a parent. The elder Leake leaped from the observer's bench yelling that he objected to testimony that parental alcoholism and a hostile childhood led to his son's delusional mental state.Leake, 30, has pleaded not criminally responsible for his actions.

After the conclusion of testimony, Judge Peter J. Messittes denied a defense motion for acquittal and one for a directed verdict of not responsible. Messittes ruled that the jury could decide whether Leake was legally responsible, despite the uncontradicted testimony of six psychiatrists and psychologists that he was suffering delusions at the time of the takeover of the temple of The Church of Jesus Christ of Latter-day Saints.

The prosecution has called police and other lay witnesses who have told the jury that Leake appeared sane on the day of the takeover and understood what he was doing.

The final defense witness, Dr. Neil Blumberg, testified Thursday that he felt Leake's delusions prevented him from understanding that his actions were illegal inside the temple. Blumberg conceded that Leake's drinking a Coca-Cola in the temple violated the teaching of the LDS Church that such caffeine-containing drinks should be shunned. He said Leake would have been criminally responsible for that act, if "drinking a controlled dangerous soda were a crime."

The state has charged that Leake entered the temple with two handguns because he was angry with the LDS Church. As evidence, prosecutor John McCarthy called Detective Jane Bowes, who testified that after the arrest Leake said he was fearful of being shot "like Lee Harvey Oswald," and at one point said he thought "the Mormon hierarchy" was out to get him.

Messittes set closing arguments and instructions to the jury for Friday. The case was then expected to go the jury for deliberations, Messittes said.
