EUGENE, Ore. -- A mother is searching for answers after the man accused of killing her baby was found not guilty.
Kelsyn Oetken was only four-months-old when he died back in 2012.
Seven years later, there's still no clear answer as to how it happened.
Last week Tyler Doyle walked in the doors of the Lane County Courthouse a man accused.
Doyle was charged with first degree man slaughter after the sudden death of a four-month-old infant back in 2012.
Wednesday, he walked out a man acquitted.
Now, Kelsyn's mom Rhiannon is speaking out saying she is exhausted, defeated, but still motivated to keep fighting for justice for her son.
"I just want Kelsyn to get his justice. Honestly I just feel broken and I feel defeated," said Rhiannon. "At the end of the day it doesn't matter what happened in court - this was about Kelsyn. It is about Kelsyn."
How do you deal with the death of your child? Rhiannon says you don't. Seven years since her baby was taken from her, she says she is still begging for answers.
She says that the case went cold due, in part, to the detective who was working the case leaving the Eugene Police Department - something she said she didn't know until months after the fact."
"After Kelsyn passed away I moved 20 times in three years because I just - I didn't know. Honestly I just was lost."
She says in the beginning she had nothing but the utmost faith in EPD that they would deliver justice to her son.
Something she says disappeared over time.
Now living in Alaska, says the healing process hasn't even began.
"Honestly the last seven years - the only thing I've held on to was I have to keep going I have to get justice for my son."
She says that she is still so angry, but she also says she's afraid of the day that anger leaves, because then she'll be forced to confront her grief.
