KALAMAZOO (WKZO) -- Initially, police said only three suspects were involved in the April 5th home invasion at Concord Place Apartments that left three young men wounded, and that all of them were in custody.  Now, a fourth suspect has been identified and law enforcement is seeking the public's help in finding him.

A warrant has been authorized for the arrest of Tyshaun Robinson in the triple shooting case.  He is wanted on three counts of attempted murder and three counts of armed robbery.

Detectives have been in contact with Robinson by phone to try talk him into surrendering on his own, but so far he has not.  They say that Robinson should be considered armed and dangerous and should not be approached.
