SALT LAKE CITY -- The family of Kayelyn Louder is still waiting for answers, but fears the case could go cold.
The 30-year-old Murray woman went missing in September, and was found months later in the Jordan River.
The cause of her death is unknown, but her family said the circumstances surrounding her death are suspicious.
“The police have told us from the beginning they don't expect foul play, and we feel completely the opposite, we kind of feel like we are left to figure this out,” said Amy Fugal, Louder’s cousin.
The family figures there's no other way to explain how Louder got from her home in Murray to the Jordan River without using her car.
And they said she didn't have bruises, scrapes or decomposition that would come if she fell in the creek behind her house and floated five miles to where she was found in the river.
“We studied the creek and the river and walked up and down both of those and studied water levels and water flows, we've seen the debris and the flow not being capable to carry her for that long,” Fugal said.
And after seeing the body, the family also worries that the autopsy wasn't thorough enough--especially for a possible homicide investigation.
“Her body was filthy, it had moss, and dirt and leaves that we were really surprised were not cleaned up to examine her body really thoroughly to see if there were cuts or wounds or even bruising," Fugal said.
The family is waiting to get those autopsy results, which they hope will tell them more. In the meantime, they’re following up on tips.
Early on in the investigation, police said Louder seemed disoriented and confused, based on 911 calls and surveillance video captured of her before she went missing. FOX 13 News reached out to the Murray Police Department Sunday, but didn't hear back.
