GRANITE FALLS, Minn. - A 28-year-old man wanted for questioning in the aftermath of a fatal shooting in this western Minnesota town remained at large late Monday night.

The Minnesota Bureau of Criminal Apprehension took the unusual step of releasing a photo of Andrew Dikken, a 28-year-old Granite Falls man, and naming him as a person of interest in the investigation.

Neighbors told KARE the shooting victim is a 26-year-old woman who works as a hair stylist in Montevideo, and has a four-year-old daughter. The little girl was not in the home at the time of the shooting.

A second gunshot victim, a 28-year-old area man described as the victim's boyfriend, called police at 3:30 a.m.. to report the attack.

He was taken to the hospital in Granite Falls in critical condition, and was later transferred by helicopter to Hennepin County Medical Center in Minneapolis.

Granite Falls Police Chief Russ Bluetold KARE thatsurveillance camera video revealed that Dikken stopped at a convenience storenear the crime scene,a few minutes after police received a call from the survivor.

"We responded to the call within minutes, at approximately the same time Mr. Dikken was just down the road at the Casey's General store," Chief Blue said.

Dikken may be driving a brown 1996 GMC Sierra pickup truck with an extended cab and a topper style cover on the bed. The truck may bear a Minnesota license plate with the numbers 032 GGL.

Investigators have yet to reveal the identities of the two shooting victims, or to discuss what may have sparked the attack.

A store clerk a fewblocks away from the crime scenetold KARE Monday nightthat a local police officer asked about the victim on Sunday afternoon, 12 hours before she was killed.

Blue is advising the public to call police if they see Dikken, rather than approach him.

"We have to assume he's armed and dangerous, and dangerous to the public at large," said Blue.

The victim's home, in the 1100 block of Prentice Street, is part of a tree-lined avenue of well maintained houses along the north bank of the Minnesota River, on the east side of Granite Falls.

A BCA mobile crime law van sat parked outside the shooting victim's home through the day on Monday, leaving shortly after 9 p.m. Neighbors and relatives walked in and out of the yellow crime scene perimeter tape, but none would comment on the record.

Several area residents said Dikken had been working in Alaska for several months prior to Monday's incident.

"That's apparently the case, that he's been on the road for the past six months or so," Chief Blue explained.

"So he could be anywhere."

Police are asking anyone with information about Dikken's whereabouts to contact the Granite Falls Police Department, the Yellow Medicine Sheriff's Office, or 911.

"This is rare for Granite Falls," the chief remarked.

"We have had a homicide in the past, that was, I'm guessing 14-15 years ago. And I can't recall how far back the previous one was, if there was one."
