San Francisco police on Friday announced an arrest in two homicides that had gone unsolved for nearly 20 years.

Roy Donovan Lacy, a 38-year-old man currently serving time in a Florida prison on bank robbery charges, has been identified in an arrest warrant as the suspect in two cases dating back to 1999 and 2000 and will be brought back to The City to stand trial for murder, according to police. The arrest was first reported in the Bay Area Reporter.

Lacy is accused of fatally stabbing former University of Nevada, Las Vegas swimmer Kameron Sengthavy, a 25-year-old man who was found dead at the Alisa Hotel in the 400 block of Bush Street on Dec. 9, 1999.

Police at the time said it appeared Sengthavy may have been stabbed inside his room and then crawled outside, where he was found around 7 p.m. No suspect was ever publicly identified.

Lacy also faces charges in the June 1, 2000 shooting of Thomas Lee, a 60-year-old San Francisco resident who was shot at a gas station at Washington and Van Ness streets where he worked as an attendant.

Police did not specify how Lacy was connected to the homicides, but said he previously lived in the Bay Area and had been brought back to Marin County to stand trial for bank robberies that occurred in 2012 and 2013. In 2014 he was convicted in Marin County and then transported back to Florida to complete his sentence there.

He will be extradited back to San Francisco to stand trial in the two murders. After those trials are concluded, he will return to Florida to complete a nine-year sentence, then go to Marin County to serve out his 105-year sentence for the bank robberies, before serving any sentence connected to the murders.
