KOOTENAI COUNTY, Idaho --- Police are asking the public for help in the investigation into the death of a mother and her two children found in a submerged car at the west Fernan Lake boat launch last fall.

Misty Phelps, 25, and her two children Tristan, 1, and Riley, 2, were found deceased in their submerged car just before 11 a.m. on Nov. 3, 2016, Kootenai County Sheriff’s Office said.

Now, detectives are hoping to identify the people and vehicles that used the boat launch the night before between the hours of 8 and 10:30 p.m.

KCSO said detectives are specifically seeking contact with the driver of a dark colored SUV seen leaving the area at 10:08 p.m.

The car is described as a dark colored SUV, possibly a Ford Bronco, late 1980s to early 1990s model with Idaho plates. KCSO said the vehicle had custom headlights and custom LED lighting near the headlights that are color-tinted or color shifting and distinctive in appearance.

KCSO asks that anyone who has seen this vehicle or owns it contact them, along with anyone else that was at the west Fernan Boat Launch or park on the night of November 2 if they have not already spoken with detectives.

In a release, KCSO said those with information can contact Detective Sergeant Brad Maskell by email: bmaskell@kcgov.us or Detective Terry Campbell, tcampbell@kcgov.us. You can also reach them at (208) 446-2237.

Misty Phelps was an employee of the Coeur d’Alene Press. She had worked in the company’s manufacturing facility since August of 2013.

KREM 2 spoke with the father of the children, Tyler Phelps, last fall.

“All I could ever think about was raising them, teaching them,” said Phelps at the time. “They were good kids. I think that they would’ve really changed lives.”

Body found in Fernan Lake.
