The four victims were shot several times shooting scenes, Chief Superintendent Ghalib Bhayani of the Lower Mainland District Royal Canadian Mounted Police said at a news conference Monday.
Langley Royal Canadian Mounted Police earlier said the suspect was in custody and investigators believe he is the sole suspect.
Both people who died are men, Bhayani said. A woman is hospitalized in critical condition and another man was shot in the leg, he said.
The incident began around midnight with the discovery of the first victim and ended around 5:45 a.m., after police engaged the suspect, according to Sergeant David Lee of the Integrated Homicide Investigation Team.
An emergency alert issued just after 6 a.m. said the victims may have been passengers, but Lee did not confirm the accuracy of that statement.
The shooting “was fleeting in nature, not necessarily people,” Lee said. “These people were targeted, but the nature of their relationship to the shooter – we are still trying to determine that.”
The Mounted Police Integrated Homicide Investigation Team, which is investigating the shooting of the victims, identified Goggin “to further identify witnesses and advance the investigation,” according to a police statement.
The police force’s Independent Investigations Office (IIO) is separately investigating the police shooting of Goggin, the statement said.
Goggin was “known to police but had non-criminal contacts,” the statement said.
Jessica Bernardo told CNN she was driving to work when several police cruisers pulled up in front of her vehicle and stopped traffic at the corner of 200 Street and 10 Freeway in Langley.
“They (the police) started running with guns,” Bernardo said. “I noticed to my right that they had someone on the ground.”
Bernardo said police blocked traffic for about 15 minutes before allowing drivers to pass.
Authorities had issued an emergency alert, warning residents of potential danger, until police were able to determine if the suspect was acting alone, police said. A later alert said they had the only suspect in custody.
In Canada, the National Public Alerting System is used to provide “potentially life-saving, area-specific (geo-targeted) warnings,” according to its website.
