SPOKANE, Wash. -

The mother of a Spokane toddler, who died from blunt force trauma to the head, is speaking out about the death of her 18-month-old son, Rylee Castner.

Rylee died on March 31st.  On Monday the Spokane Medical Examiner ruled his death a homicide.

Rylee's mother, Cassie Castner, says on March 30th Rylee was fine when he woke up. Later in the morning, Cassie says she took a shower and made breakfast so her boyfriend watched Rylee and her other son downstairs.

"I heard some crying but it wasn't like painful crying, it just sounded like he was being cranky," Cassie said.

Cassie says the crying only lasted a few minutes. When she came downstairs a little while later, Rylee was asleep in his crib. She took the sleeping toddler to a barbecue and things quickly took a turn for the worst.

"We took him to the barbeque and immediately went and talked to my mom and had her check him out when we started seeing the bad signs and bruising we called 911," Cassie said.

At the barbeque, the family noticed blood coming from Rylee's mouth and bruising on his cheeks. The family tried to wake up Rylee but he was unresponsive and died at a hospital the next day.

Through this tragedy, the toddler is touching other. Rylee's organs helped save three people's lives.

"He should be known as a hero because he saved people," Cassie said.

Rylee's funeral is set for Thursday.

As for this investigation, police say it is ongoing and they haven't made any arrests yet.
