NEW HAVEN, Conn. — A Yale Medical School professor whose dogs mauled a Connecticut woman to death is facing drug charges.

WTNH-TV reports Hamilton Hicks will be in New Haven court Friday. Police say he had three bags of crack cocaine in his possession during the June 20 dog attack that killed 53-year-old Jocelyn Winfrey.

The 36-year old Hicks has not been charged in the dog attack, however. Police say they’ve closed their investigation, and the dogs were properly registered and vaccinated.

Winfrey had been visiting Hicks’ home when the dogs attacked. Hicks tried unsuccessfully to pull the dogs off Winfrey, who later succumbed to her injuries.

WTNH-TV says the dogs will be euthanized next week. Hicks and Yale Medical School haven’t commented.
