Residents of Heritage Grove Apartments in the Highlands were victimized again four days after a two-alarm fire in their building, when early Tuesday, several apartments were burglarized.

The Renton Police Department is investigating the burglary at 1100 N.E. Sunset Blvd. Meanwhile, the cause of last Friday’s fire has yet to be determined. As of mid-week, fire inspectors were still gathering data and conducting interviews.

Investigators were waiting on results from the state lab and preparing to interview several of the occupants of the building, one of whom was recently released from Harborview, according to Deputy Fire Chief Bill Flora.

Damage to the Heritage Grove Apartments has been estimated at about $750,000, according to Renton Fire and Emergency Services.

Residents are still not allowed in the building, which will be unoccupied for some time depending on the insurance and construction needs, according to the fire department.

Most of the residents have been relocated.

The temporary shelter that the Red Cross set up after the fire has closed, but the agency continues to provide assistance to fire victims.

They have been assisting 22 families from the apartment building, including assistance with shelter, food, clothing and other immediate needs.

The Renton Fire and Emergency Services determined the fire-alarm system was functioning properly during the two-alarm apartment fire that injured two residents.

There were earlier reports of confusion among residents as to whether the apartment alarms where working. It took two hours to put the blaze out and another two hours to put out flare ups and hot spots, according to the fire department.

Fire units arrived to find flames coming from the third-floor windows and two patients on the ground outside, according to the fire department.

The fire was quickly upgraded to a two-alarm fire, with fire crews coming from Kent, Tukwila and Skyway.

The patients were treated at the scene and transported to Harborview Medical Center with non-life-threatening injuries.

The fire heavily damaged six units of the 24-unit building and heavy smoke damaged another 12 units. The remaining six units sustained some smoke damage as well.

According to the fire department, 24 of the residents were sheltered by the Red Cross at the community center last Friday. The remaining residents found accommodations with friends or family.

Resident Ray Gage, 61, said he was surprised and puzzled when he woke up to the sound of fire crews hosing down the building at about 2:55 a.m. He said he was probably one of the last residents out of the building.

“I didn’t hear an alarm or anything,” he said. “I’m a sound sleeper, so it takes a lot to wake me up. I grabbed my clothes and ran out the door.”

Gage was immediately met by two firefighters who escorted him outside. He learned the source of the fire was upstairs and to the left of his apartment.

Gage said the smoke alarm in his apartment didn’t go off; he suspects the reason is that there didn’t appear to be enough smoke in his apartment.

He was one of the residents to seek assistance from the Red Cross, to whom he feels grateful. Gage drove down to the Renton Community Center later last Friday morning to seek support and wait for word from the apartment property manager and his insurance company.

“We fed about 58 individuals, that included firefighters and clientele,” said Vicki Lee, Mass Care Shelter Lead for the Red Cross. “They decided then that they needed to open up a shelter because the units are burned. They can’t go back into the units.”

The Red Cross arrived at the apartment fire a little after 5 a.m. and opened up the temporary shelter at the Renton Community Center around 8:30 a.m.

The organization worked with the apartment management and other apartment complexes in the area to assist with finding new homes for those displaced by the fire.

The Renton Police initially assisted with telling residents about the fire, prompting those who did not respond to the alarms to evacuate their units. Police also assisted with traffic control, as Northeast Sunset Boulevard was closed for several hours.
