Ferndale — Police said Monday more investigation is needed into a man's killing at a dollar store in 2010.

They said a suspect who was arrested Thursday in connection to the crime has been released.

Ferndale police officials said the Oakland County Prosecutor's Office told detectives late Friday the case they had submitted in the 2010 murder of Karim Khamarko did not contain sufficient evidence to issue an arrest warrant at this time.

"We appreciate the careful consideration of our Prosecutor’s office as they spent hours examining the evidence our detectives brought them," Ferndale Police Chief Vince Palazzolo said in a statement. "We are ever mindful of the interplay of checks and balances designed into our criminal justice system that seeks to ensure the fair application of due process for those accused of crimes. We will have no further comment as this case remains an open and active investigation."

On Thursday, Ferndale police arrested a 48-year-old man from Romulus after receiving a tip earlier this year and re-examining the case.

Khamarko, 64, was shot and killed at his store, the Dollar Club Plus at 2750 Hilton in Ferndale, on Nov. 26, 2010. A witness called 911 after finding him on the floor, bleeding and having trouble breathing. He had been shot multiple times.

Detectives followed up on many tips and leads throughout the initial phase of the investigation but none led to an arrest. At one time, a Crime Stoppers reward for $20,000 was being offered for information into the case. 

Khamarko's family closed the dollar store in 2011 after the incident.
