The Warren Police Department is investigating the homicide of a 27-year-old Warren resident and the critical stabbing of his twin brother.
Officers arrived at the 20800 block of Atlantic on Friday night and saw two victims on the sidewalk with stab wounds.
One of the victims and multiple witnesses identified the attacker as a 40-year-old man named "Chavez."
According to the witnesses, there have been ongoing problems between the victims and "Chavez" during the past week.
The witnesses report that the suspect is a known drug dealer on 8 Mile. Earlier Friday evening, the victims and "Chavez" were reportedly engaged in an argument at a party store on 8 Mile and Mound.
Police say it appears that the suspect followed the victims to the residence on Atlantic where the attack occurred.
The victims were transported to the hospital where one later died of his wounds, and the second is listed in critical condition.
Warren detectives identified "Chavez" as Johnny Lee Whitfield, 42. He is described as an African-American man, 5 feet 8 inches, 135 pounds with black hair and brown eyes.
Whitfield has family in Warren and Detroit, but his last known address is in Toledo, Ohio.
"This is a tragic situation, but we believe that with the public's help, this dangerous suspect will be quickly located and taken off the streets," Warren Police Commissioner Bill Dwyer said.
"I want to reassure the public that this incident appears to be a result of an ongoing feud and that the City of Warren remains a safe place to live and work."
Anyone with information on the location of Whitfield is asked to contact the Warren Police Department at 586-574-4877.
