Police launched a nationwide manhunt Gerald Michael 'Mike' Bullinger (pictured), a 60-year-old pilot, after the decomposed bodies of three women were found in his Idaho farmhouse on Monday, June 19

A retired pilot is on the run after he allegedly killed his wife, mistress and her teenage daughter at a rural property in Idaho, then lining up their dead bodies in a shed and covering them in plastic before fleeing the scene.

Idaho police stated last week they are searching for 60-year-old pilot Gerald Michael 'Mike' Bullinger, formerly of Utah, after the badly decomposing bodies of three slain women were discovered in a shed on Monday, June 19.

He is a suspect in the three murders and has been charged with failing to report the deaths after the bodies were found covered by plastic by authorities in a shed on a Caldwell property the 60-year-old purchased with his wife last month.

And now friends of Nadja Medley, 47, and her 14-year-old daughter Payton, have spoken out to say they believe two of the bodies found belong to the mother and daughter.

Rebecca Lorenz, of Ogden, Utah, told the Idaho Statesman she feared the worst having not heard from her 47-year-old friend since May 23.

Lorenz added Medley had recently moved in with Bullinger - who she had been dating for two years, but did not know he was married.

'She was head over heels in love with Mike,' the upset friend told the Statesman.

Social media accounts belonging to Medley show she excitedly discussed moving from Utah to Idaho last month - after she was asked by 'Mike'.

In March, she wrote: 'WE’RE MOVING. That’s right. A new home has been found, and Mike, Payton Medley and I are moving in together. Boise, here we come!'

Then on April 20 she put a call-out for dinner recommendations, posting: 'BOISE PEEPS: Need recommendations for the best Sushi in town. We're moving up there the beginning of May, have found really good everything else, but sushi is just NOT trial and error. (All other food recommendations are welcome too, particularly diners. We'll be in Caldwell, but don't mind driving for grub!)'

'Well, we're on our way to Boise. Dogs, cats, bunnies, chickens, fish, birds, snake and people. One helluva packing adventure! Holy crap....,' she wrote on May 3.

Then on May 10 she shared a video titled, Our New Place, that showed the property - including a wooden shed near the house.

She had mentioned the move even further back, writing in March 2016: 'OK folks, I have some news. Mike asked Payton and myself to move to Boise with him once his new job is stable and he’s settled in a bit. It’s not an immediate thing, but we’re working on getting the house in order and things settled.'

Social media pages for both Nadja and Payton have been changed to serve as memorials for friends and loved ones who are 'remembering' them.

Nadja's second-to-last Facebook post was a picture of her daughter, face painted for a pride parade.

The caption for the image read: 'Love this kid to death.'

KTVB reports the last time either Nadja or Payton were heard from was June 8.

It was also revealed by one of Payton's friends that the 14-year-old called Bullinger 'dad', and the teen had told her the suspect and Medley were engaged.

Bethany Cagle, 15, told KUTV about the alleged engagement, adding she was shocked to hear the news her friend and mother were believed to have been shot dead.

It comes after it was reported last week officers searched the property after one of Bullinger's relatives called police to ask for a welfare check, saying the family hadn't been heard from for a few days.

Bullinger, a pilot, was said to be in the process of moving to the property with his 57-year-old wife, Cheryl Baker.

Baker has still not been heard from.

The 60-year-old suspect allegedly moved to Idaho with Medley and her daughter, both of whom were unaware Baker was also going to be moving to the property a short time later.

Canyon County Sheriff's Chief Deputy Marv Dashiell said the officer who first searched the property began looking in the shed after sensing something was amiss.

That is when the deputy discovered a gruesome scene: A shed on the property held the three bodies, each laying side-by-side and hidden under some sort of plastic covering.

Several dead birds and dogs - likely family pets - were also found on the property, and other living animals including a snake, rat and some rabbits were removed during the subsequent investigation.

The animals appear to line up with those mentioned by Medley is her social media post about moving to the property.

At first, investigators couldn't determine the gender of the bodies or what killed them, but autopsies completed last Tuesday revealed the three women had each been shot once.

The women had been dead for one to two weeks before their remains were found, Dashiell said.

Records show Bullinger took ownership of the property on May 3, CBS News reports.

Police are actively seeking Bullinger, Dashiell said, and believe he may be driving a white 2007 Ford Focus with Utah license plates numbered 129UMP.

Baker's brother, Byron, told the Idaho Statesman he thought his sister and brother-in-law were still in the process of moving from Utah to their new home in Caldwell when family members became concerned because they hadn't heard from them.

He added he thought the couple lived alone, and was unsure who anyone else at the home might be.

'I just don't know what to believe,' he told the newspaper. 'There are four people involved here. Three bodies and someone who covered the bodies.'

Canyon County Sheriff's Chief Deputy Marv Dashiell said last Wednesday the women had been dead for one to two weeks before their remains were found

He also described a strange text his sister had sent to a close friend in Utah around June 11, which read: 'Take care of my dogs. I don't know if I'm coming back.'

Cheryl Baker had just retired from her job as an art teacher at Greenwood Charter School in Harrisville, Utah, and Bullinger was a pilot with Classic Aviations Service in Utah before taking on contract work in Idaho.

Neighbors of the Caldwell home reported hearing a gunshot or other noises about two weeks ago, but gunshots aren't uncommon in the rural area, where many avid hunters and target shooters live.

One neighbor, Cindy Morrison, said she heard a loud scream early one morning sometime around June 6 to June 10, but wasn't sure at the time whether it was an animal or a woman who made the noise.

She did not hear anything else, and opted not to call police.

Investigators confirmed last week the women ranged in age from mid-teens to late 50s, and their ages and statures matched the description of people thought to have been living at the home.

They have not confirmed the identities.

Bullinger was last seen in Ogden, Utah, on June 12.
