At issue is whether Mary Robbins’ head and brain will be preserved by cryonics — extremely cold temperatures — in the expectation that future technology may be able to bring her back to life and restore her health.

She signed a contract giving her remains to Alcor Life Extension Foundation of Scottsdale, Ariz. in 2006. But her family says shortly before she died she asked to cancel that arrangement.

Alcor argues that Robbins never signed a document canceling contract.

Robbins died of cancer Feb. 9. Her body is being stored on dry ice at a Colorado Springs mortuary until the case is settled.
