A joint investigation by Calgary and Edmonton police into two targeted shooting incidents in 2016 has identified four people who may have information on the homicides.

Cuc Lung, 34, and Quang Tran, 38, were shot while sitting in a vehicle outside a residence on Redstone Manor N.E. at about 8:00 p.m. on September 20th, 2016.

Police say Lung’s five-year-old son was in the backseat at the time and was uninjured in the shooting.

“It’s a great concern not only to police but citizens when innocent people and children get involved in these unfortunate, violent attacks," said Acting Staff Sergeant Kurt Jacobs of the Calgary Police Service homicide unit. "The child, to my understanding, is still with family and doing well considering the circumstances.”

On October 7, 2016, Emergency crews in Edmonton were called to a shooting near 171 Avenue and 126 Street at about 8:00 p.m.

Phu Phan, 30, was found dead in the driveway of his Rapperswill residence and police say he died from multiple gunshot wounds.

Investigators believe the two shootings were carried out by an organized crime group and that the victims were targeted.

“We do believe this attack was orchestrated by a known organized crime group based out of Calgary,” said Jacobs. "Obviously, this wasn’t a random attack. It was planned, it was deliberate and obviously it was more than one individual purposely committing this attack for criminal purposes.”

According to Jacobs the persons of interest who appear in surveillance camera images from undisclosed locations are different individuals than previously identified persons of interest in the investigation into the homicides.

“These are definitely persons of interest to us like the other ones were," said Jacobs, "We have information that they could be related to some of these offences but, in saying that, it’s still too early in our investigation and we’re seeking the public assistance to confirm their identities, number one, and also, number two, someone in and around the time of these homicides might recognize them as to what they were driving, where they were going.”

“Any information to confirm their identity and their whereabouts around these homicides would be very useful to us.”
