The remains of Sam Lamar Lucas, 77, and his wife Linda M. Lucas, 76, were found inside a home in the fire area.Authorities say one of them was found outside the home and another was found inside the home.

The causes of death are being investigated by the Jefferson County Sheriff's Office, but no other information is being released at this time.

Anunidentifiedwoman has been reported missing. No description of the missing woman has been provided. Police say the person is missing in the area of Kuehster Road.

The fire has damaged or destroyed 23 homes and has consumed 4,500 acres and authorities say it did notadvance on Tuesday evening. About 900 homes have been evacuated since the fire began.

"The priority has been structure protection, and if we have to chose between fighting the fire and taking care of homes, that's what we're going to continue to do, and that's what we had to do a lot today," Jefferson County Sheriff's Office spokesperson Jacki Kelley said Tuesday afternoon.

On Tuesday night, the sheriff's office said the effort is still focused on protecting buildings.

Jefferson County Sheriff's Office Dispatch sent out a pre-evacuation notice to 6,500 homes Tuesday afternoon - located in regions north of the existing evacuation area:

  • Dear Creek Mesa
  • Deer Creek Canyon Park
  • Homewood Park
  • Hilldale Pines
  • South Murphy Gulch Road
  • Watson Gulch Road
  • South East of S. Turkey Creek Rd
  • White Deer Valley
  • Jennings Road

Kelley says there is zero containment of the Lower North Fork Fire.

Kelley says the 900 homes evacuated are north and east of the fire. The currently evacuated subdivisions include Oehlman Park and Conifer Meadows north of Foxton Road.

Fire crews were out all Monday night and Tuesday focusing on structure protection, says the Jefferson County Sheriff's Office. More resources were brought in Monday night to help fight the fire, and a Type I Incident Command team will arrive by Tuesday evening. Kelley says the team is the same one used to fight the Fourmile Canyon Fire in September 2010.

Kelley says about 450 more firefighters are on the way from various parts of the country to help battle the blaze. Hot Shot fire crews are on the way from Utah, Arizona and South Dakota. They will be immediately deployed to fire line when they arrive.

Air support arrived and the planes were able to make slurry drops on the blaze.Air support consisted of a SEAT and a heavy P2V airplane dropping fire retardant over the fire.Two National Guard helicopters from Buckley Air Force Base dropped water also.

Two helicopters, a Heavy P2V Aircraft and Single Engine Air Tanker are scheduled to continue dropping retardant on the fire area on Wednesday.

The fire is burning in an area near Conifer on Buffalo Creek Road near Foxton and River roads. Officials say the fire is burning on the ground with some fire in the trees.

Jefferson County Sheriff's Office created an interactive Google map of the fire perimeter andevacuationarea.

Evacuated residents were asked to go to Chatfield and Conifer High Schools. The American Red Cross was helping the evacuated residents. Tuesday morning, Chatfield was closed as an evacuation point since the need was no longer there.

Tuesday, all the evacuees at Conifer High School were transferredto West Jefferson Middle School because the firefighter command center moved into the high school.

Kelley says lots of animals were left behind.

"Jefferson County Fairgrounds is currently housing 69 horses, 30 alpacas and llamas and two cows.In addition, 22 small animals were sheltered over night at Conifer High School," the sheriff's office said.

Large animals evacuated due to the fire can be taken to the Jefferson County Fairgrounds. Anyone who needs help with the evacuations can call 303-277-0211.

Kelley says the fire is from a prescribed burn by the Colorado Forest Service that was set last week and "escaped" about 2 p.m. on Monday.

The Colorado Bureau of Investigation is looking into thecircumstancesinvolvingthe origin of the fire.

CenturyLink and IREA will be given access to the fire zone on Wednesday to evaluate utility damages.

Gov. John Hickenlooper is on a trip to Mexico, and told 9NEWS on Tuesday he had not yet decided if he would cut his trip short because of the Lower North Fork Fire.

"We have the National Guard standing by, again depending on whether we're asked," Hickenlooper said. "A key part of all of this is to make sure we don't impede the ability of the local government to fight this fire, so we are trying to be supportive and provide assistance as appropriate."

Hickenlooper says he may consider a ban on prescribed burns similar to the one Gov. Bill Owens issued in the summer of 2002.

"We're certainly going to look at that. You know, the reason we keep doing planned burns is because if you don't have a planned burn you run into a real problem, you end up with much larger fires that cause much more damage," he said.

Hickenlooper says one way for people to help keep their homes safe is to do fire mitigation themselves.

"Our real problem is in places like suburban Denver and suburban Colorado Springs where people are attracted to the natural setting they've built their houses up in the forest and now with all the dry tinder all the fuel that's there, there's some considerable risk. So we're trying to encourage people to clear out the trees around their home," he said.

He says he also supports increased forest thinning on state and federal lands.

"We have endorsed that from the beginning. We have been trying to get more money, repeatedly, from the federal government to try and support those, not just forest thinning, but really beginning to deal with the beetle kill. The problem, as the US Forest Service is the first to point out, we're not talking 10,000 acres or even 50,000 acres. We're talking about millions and millions of acres," Hickenlooper said.

Elk Creek and North Fork Fire Departments responded early and the U.S. Forest Service sent two hand crews to help fight the fire. The fire started burning on Denver Water Board land. At least 15 fire departments responded originally to the fire. FEMA funds were approved to help fight the fire on Monday night.

Due to the fire, South Foxton Road is closed from Reynolds Ranch south to the river. Forest Road 550 is also closed to Buffalo Creek. Pleasant Park Road is closed from Highway 285 to Deer Creek Canyon.

Kelley is asking anyone who is looking to help to not send food to the fire location.

"Because of the generous food donations, out of control generosity coming into this place, it is more than we can eat. We are asking people who want to do something to not donate food to this location any longer," she said.

United Way Denver is accepting donations to help victims of the fire. More information can be found or by calling 211.

If you want to volunteer or make a donation, the Jefferson County Sheriff's Office asks that you go to, or call 866-760-6489. They say the best way to help for now is to provide a financial donation.

Smoke from the fire was visible from Denver on Monday.

Authorities say if visibility is less than 5 miles in smoke in your neighborhood due to a wildfire or controlled burn, smoke has reached levels that are unhealthy. If smoke is thick or becomes thick in your neighborhood it's recommended you stay indoors. This is especially important for people with heart disease, respiratory illnesses, the very young, and the elderly.

Because of the high risk of fire, the following counties and cities have burn bans in effect:

  • Unincorporated Arapahoe County (Includes Cherry Creek State Park and Centennial)
  • Boulder County
  • Golden
  • Englewood
  • Denver Mountain Parks

An open-burn ban generally prohibits the following: outdoor fire, including, but not limited to: campfires; warming fires; fires in outdoor wood-burning stoves (chimney sparks); and the prescribed burning of fence lines, fence rows, fields, farmlands, rangelands, wildlands, trash or debris, chimineas (outdoor clay fireplaces) and fireworks.

The restrictions and allowances differ for each area. For more information on a burn ban in your area, contact your local authorities.
