Police are investigating the death of an Eagle River man as a homicide. The victim is 32-year-old Andrew Conn.

An unidentified witness told police they tried to get in contact with Conn by phone all afternoon Saturday and eventually gave up and headed to the Mountain Vista Drive house where he lived.

The witness made a gruesome discovery, and neighbors called police around 5 p.m.

Details from the crime scene are few, and what exactly happened remains unclear, but investigators are convinced the death was a possible homicide.

Sgt. Slawomir Markiewicz, a homicide detective for the Anchorage Police Department, said “the nature of the injuries and appearance of the scene indicated to (investigators) that someone else was likely involved.”

Markiewicz declined to comment on specifics about the injuries.

“A lot of times for an experienced officer, or for a well-trained officer, it’s apparent” that foul play led to a death, he said.

Investigators were busy knocking on doors Sunday. They asked residents if they know what happened or saw anything out of the ordinary in the hours leading to the discovery of Conn’s body.

Police also ask anyone with information to come forward: tips can be directed to APD at 786-8900 or anonymously to Crime Stoppers at 561-STOP.

A neighbor who asked to remain anonymous said Conn lived at the two-story house for a few months.

Residents described Eagle River – and the Mountain Vista neighborhood in particular – as peaceful, calm and usually free of crime.

“We had some concerns when me and my best friend moved here, so we asked around,” said Jane Cox, who has lived nearby for two-plus years.

Everyone said Eagle River is the place you want to live, and in particular, up on Mountain Vista. It's a great neighborhood.”

“I didn't think that would ever happen in a place like this,” said David Majchrowicz, another nearby resident. “It's a nice neighborhood … lots of kids, really family-oriented.”

Homicides are up this year across Anchorage. APD spokesperson Jennifer Castro says Conn’s death marks the 20th person this year whose death has been investigated by police as a homicide, including three people shot by APD officers in the line of duty.

Fifteen people were killed in Anchorage homicides, excluding officer-involved shootings, in 2012. The city's five-year average is 12.8 homicides annually.
