A 31-year-old former homeless man pleaded guilty to murder and was referred to a state mental hospital for the killing of a 57-year-old former roommate in August 2000.
Vladislav N. Filatov, who has a history of psychiatric problems, was found by Judge Clifton J. Gordy on Friday to be not criminally responsible for the stabbing death of Richard F. Kondner, an interior designer, in a condominium on East University Parkway near the Johns Hopkins University.
Filatov also pleaded guilty to attempted murder for stabbing but not killing another former roommate, Michael A. Jordan.
Filatov will be treated at Clifton T. Perkins Hospital, a maximum security state psychiatric institute in Jessup.
Filatov had roomed briefly with Kondner and Jordan in Jordan's condominium, but they asked Filatov to move out. On Aug. 8, 2000, police said that he returned and fatally stabbed Kondner and wounded Jordan.
Sixteen months earlier, a District Court judge had found Filatov not criminally responsible for carrying a deadly weapon and malicious destruction of property and ordered him to undergo psychiatric care at Union Memorial Hospital. He had been accused of smashing the rear-view mirrors of eight cars near Hopkins and waving a 6-inch knife.
