PORTLAND, Ore. -- Three murders in two weeks and no suspects behind bars have left East Portland neighbors worried, anxious and upset.

Tuesday night they packed a town-hall meeting with Police Bureau detectives and administrators to vent frustration and demand answers.

Neighbors want arrests. If the crimes aren’t connected, as police have indicated, three different killers could be roaming their neighborhood.

"My biggest concern is these kids going to school with maybe three maniacs going around killing people. I have two kids so it’s really scary, especially the murder right next door, my next-door neighbor,” Yvonne Coronado said.

Locals said the turnout was three times that of a normal community meeting.

The killings began Nov. 14 when Amanda Mendive Boyle was found near Freedom Foursquare Church at SE 160th Ave. and SE Stark St.

Nine days later and three blocks away Abel Delgado Morales, 35, was shot to death in an apartment.

And last Saturday Roland Dir, a delivery person, was found dead near SE 155th Ave. and SE Stark St.

Moe Farhoud owns 11 apartment complexes in the area. He said tenants are ready to move -- and he wants action from police.  

"We have at least 20 calls a day, every day, from our tenants, ‘Have you guys heard anything from the police? Do you guys know anything about it?’ People are panicking," Farhoud said.

Portland Police Bureau officials didn’t have many of the answers these locals were seeking Tuesday night.

The bureau said it hasn’t ruled out a connection between the crimes but detectives do not believe they’re related.

Portland Police Chief Rosie Sizer asked neighbors to “stay engaged” as the investigations continue -- and as officers work to prevent future violence.

Sizer said the bureau had some “very good leads,” but that detectives were awaiting forensics results before proceeding with arrests.

“Put some cops out here. They can put a stop to it if they want to,” said Ray, a man who lives in Southeast.

The recent string of violence has forced neighbors like Ray to second-guess their routines.

“I definitely lock the door each time I go into my office. And I keep a lookout. Maybe we’ll have to start a vigilante group,” added Aaron Arnold, who works in Southeast.

Location appears to be the only link, Sgt. Brian Schmautz said.

“It’s concerning that they aren’t related and we have that many individual incidents going on,” added Curt Hugo, who works in Southeast.

And until police capture those responsible, residents say they will not rest.
