Authorities are investigating a homicide at a Maple Grove rest stop early Wednesday that led to a police chase with authorities fatally shooting an armed suspect after the man crashed on Interstate 694 in Shoreview.

The incident began with police dispatched to the scene of an apparent shooting at the Elm Creek rest stop on Interstate 94 about 1 a.m. Wednesday. There they found one man dead, according to the Hennepin County sheriff’s office.

With crucial help from a witness at the scene, officers spotted a red SUV within minutes that matched the suspect’s description near the I-694, I-494 and I-94 split, Maple Grove Police Chief Eric Werner said.

The man’s vehicle had Oregon license plates, and the Minnesota Bureau of Criminal Apprehension is examining the connections, said BCA Assistant Superintendent Drew Evans.

Police from several area agencies — with the help of a Minnesota State Patrol helicopter — pursued the vehicle until it crashed into the wire median on I-694 near Rice Street in Shoreview.

The man then got out of the SUV with a weapon and was fatally shot by police; a Brooklyn Center police officer and a Hennepin County sheriff’s deputy fired their weapons, according to sheriff’s officials.

Hennepin County Sheriff Richard Stanek said the investigation is complex because of the number of law enforcement agencies involved, in addition to the complexity of the incident.

“There are more questions than answers at this point,” he said.

Minnesota BCA agents have interviewed witnesses in the I-694 shooting and processed the officer-involved shooting scene, according to Evans.

The rest-stop homicide is under investigation by the Maple Grove Police Department. The Hennepin County and Ramsey County medical examiner’s offices will handle each scene’s respective autopsies.

Both directions of I-694 were closed between I-35W in Arden Hills and I-35E in Little Canada until shortly after 9 a.m. Wednesday. Minnesota Department of Transportation officials said the closures were necessary for authorities to investigate.

The closing put traffic pressure on other east-west commuter arteries, including Minnesota 36 and Minnesota 96 — most commute times in the north metro were doubled and tripled because of the closure.

Traffic was diverted from the roughly six-mile stretch and only emergency vehicles were being allowed through during the closure, according to MnDOT.
