An Edmonton homicide detective is asking for the public’s help in cracking a four-year-old homicide case that’s gone cold.

Shawn Michael Yalowica, 19, died from his wounds after a spray of bullets struck him as he was entering Laser Karaoke near 34 Avenue and 99 Street June 20, 2006.

Police say two male suspects were seen fleeing from the area and investigators believe Yalowica was unintentionally shot in a gang-related crime.

Fran Metselaar, the lead detective in the cold file, says cracking the case has been a challenge since many of the witnesses had gang ties.

Since it’s been four years since the crime, Metselaar says he’s hoping those witnesses who “escaped the grasp of a gang” are now willing to come forward.

“This has been weighing on their conscience,” said Metselaar.

Homicide detectives believe the suspects were black or Hispanic males, but witnesses have been unable to provide a more detailed description.

Anyone with information about this case is asked to call the Edmonton Police Service at 780-423-4567.
