Two parolees are in custody on murder, assault, and drug charges for the deadly triple shooting Monday in Rochester's Beechwood neighborhood.
Police Captain Greg Bello says one of the suspects, 21-year-old Nasezire Horton already has a long record and has had his parole revoked several times.
Horton was arrested again for a parole violation as recently as last month and was immediately released.
He and 21-year-old Quentin Riviere allegedly opened fire at a teenage boy on Hazelwood Terrace.
The boy, and another teen, were wounded.
A stray bullet killed 19-year-old Rukia Isaak.
The arrests came after a raid yesterday at a suspected drug warehouse on Edmonds Street. Police seized crack cocaine packaged for sale and marijuana.
