Section 652 - Delivery of warrant and confinement1. Within ten days after the issuance of a warrant as provided in section six hundred fifty of this article, the sheriff or the commissioner of correction, if within the city of New York or county of Westchester, must deliver the warrant and the person sentenced, if that person is not already in the custody of the department, to the department or to the superintendent of the state institution designated by the commissioner. Upon the issuance of the warrant the court shall cause a copy to be personally delivered to the convicted person and shall send a copy of the warrant to the convicted person's last attorney of record.2. From the time of the delivery of the warrant and until the imposition of the punishment of death upon the convicted person, unless discharged from the sentence, such person may, in the commissioner's discretion, either be kept isolated from the general prison population in a designated institution or confined as otherwise provided by law. The commissioner, in his discretion, may determine that the safety and security of the facility, or of the inmate population, or of the staff, or of the inmate, would not be jeopardized by the inmate's confinement within the general prison population.3. The commissioner may promulgate rules and regulations concerning visitation of inmates sentenced to death. Such rules and regulations may provide that inmates sentenced to death are subject to different visitation policies and procedures than inmates who are not sentenced to death.
