The crime took on Friday, June 1, 2004, around 1:13 p.m. at 23-25 Pearl St., said Lieutenant David Silverio of the Waterbury Police.

Through investigative means, detectives identified Robinson as the person responsible and applied for and were granted an arrest warrant.
On Jan. 29, members of the Criminal Investigations Bureau located and Robinson and charged him with murder.
At the time of the crime Keyworth, who was a student at a Job Corps center in Massachusetts, had taken a train to Connecticut to visit a friend on Memorial Day.
She was found dead in the basement stairwell the next morning, said reports from the time of the murder.
