This bill provides that if a medical examiner has determined that a child under 3 years of age has died as a result of sudden infant death syndrome or if the medical examiner is unable to determine the cause of death for a child under 3 years of age, the Chief Medical Examiner must, at the request of the child's parent or legal guardian, preserve and retain sufficient tissue samples and other evidence necessary to make a subsequent determination of the cause of death for one year following the date of death of the child. Such evidence must be made accessible to the parent or guardian of the child.
