The man who was fatally shot by police on Interstate 694 in Shoreview following an apparent homicide and subsequent police chase early Wednesday morning was a high school student in Washington state.

Details on the early morning incident are still sparse, but the Ramsey County medical examiner identified the suspect as Johnathon Dean Mar, an 18-year-old of Kennewick, Washington.

In a release Thursday, the medical examiner said he died of blood loss due to multiple gunshot wounds.

KEPRTV says Mar was enrolled in the Kennewick School District for three months in 2011 and returned to the district in August. He was a senior at Legacy High School and Tri-Tech Skills Center, KVEW reports.

The incidents

At about 1 a.m. Wednesday Maple Grove police responded to a report of a shooting at a rest area along Interstate 94 and Weaver Lake Road. When officials arrived, they found an man dead at the scene, calling it an apparent homicide, the Hennepin County sheriff's office said.

That man was identified Thursday afternoon as Matthew Paul Maffei, 23, the Hennepin County Medical Examiner announced. A permanent address was not listed; he died from a gunshot wound to the head, according to the examiner.

A witness, who was able to provide detailed information, told police the suspect had left in a red SUV with Oregon license plates.

When police caught up with the suspect and tried to stop him, he led police on a chase that ended when he lost control of the SUV and hit the center median on eastbound Interstate 694 east and Rice Street in Shoreview, nearly 20 miles from the Maple Grove rest area.

WCCO, quoting police scanners, says speeds during the chase reached 100 mph.

Officials from multiple jurisdictions converged on the suspect, who got out of the car, brandishing a weapon. A Hennepin County sheriff’s deputy and a Brooklyn Center officer shot and killed the suspect.

The crash and investigation into shooting led to the closing of I-694 between I-35W and I-35E for more than eight hours, causing major backups during the Wednesday morning commute.

The investigation

“We have more questions than answers at this point,” Hennepin County Sheriff Rich Stanek said during a news conference Wednesday. “We want to get at what happened, why it happened and how it happened.”

Officials note this is a complicated investigation because it involves multiple jurisdictions. The Maple Grove Police Department is investigating the apparent homicide at the rest area, while the Bureau of Criminal Apprehension is investigating the officer-involved shooting.

Officials haven't identified the two officers involved in the shooting, but are expected to do so on Friday.

This was the first time since August 2013 that an officer with the Brooklyn Center police department has been involved in a shooting, the Star Tribune notes.

The identity of the victim will be released by the Hennepin County medical examiner.

Details about the relationship between the victim and suspect aren’t known, officials said.

Anyone with information about either incident is asked to call police.
