CENTENNIAL, Colo. — The defense in the Colorado theater shooting trial rested its case Friday after trying to show James Holmes was legally insane when he opened fire at a midnight movie and was suffering from delusions that each person he killed would increase his self-worth.

Holmes’ public defenders ended their case after playing two silent surveillance videos of Holmes taken in the months after the attack. One showed him in his jail cell, running and slamming his head against the wall, then falling backward and sitting down.

The other, taken at a hospital, showed Holmes naked and tethered to a bed, repeatedly trying to cover his head with a blanket and then a sheet. Uniformed officers and hospital workers pull them off and try to cover the lower half of Holmes’ body with them.

Jurors also read a sheaf of papers that included writing by Holmes titled “Galactic Colonization,” but the contents were not discussed in court.

The decision to rest the case ended 10 weeks of often-gruesome testimony, with witnesses describing the bloody shooting scene and their own crippling wounds and attorneys probing psychiatrists about Holmes’ mental condition.

Judge Carlos A. Samour, who on Friday denied a defense motion to acquit, dismissed the jury until Tuesday, when closing arguments and a formal reading of jury instructions will be made.
