SARATOGA SPRINGS – The man found dead last week at the Hilton Garden Inn on South Broadway was identified as Donald J. Rockenstire, whose death was possibly due to a heroin overdose. The 53-year-old man was identified this week by his son, Derrick J. Rockenstire, who has also inquired about a missing $1,040 casino voucher that was said to be in his father’s possession at the time of his death. Rockenstire said that the Saratoga Springs Police Department had told him of his father’s voucher twice before, but later said that he only had worthless lottery tickets in his possession. The department said that it is continuing its investigation regarding the reports that Donald Rockenstire had won money in the lottery or by other means the night he died.
