A Killeen baby who was found unresponsive in a bathtub almost three weeks ago passed away at a Temple hospital Sunday night.

KWTX reported the tragic news Monday. 8-month-old Landon Rasmusse had been fighting for his life in McLane's Children's Hospital since January 11.

First responders to a home on Taylor Renee Drive in Killeen were able to resuscitate Landon, and he was transported to Metroplex Hospital before being transferred to McLane's.

Police have not released details about Landon's case, but his mother wrote about the incident on a GoFundMe page set up to help with Landon's medical expenses.

I got a text from the sitter "911-Landon please". When I tried reaching her her phone went straight to voicemail. When I arrived there was police and detectives everywhere. I never got the chance to speak to the sitter. He police officers pulled me aside and told me there was an incident with Landon in the bathtub. She claims Landon threw up all over himself and that's why she needed to bath him. She said that a man was trying to come in and inspect her new home. According to her this "man" was armed and argued with him back and forth.

Why she would leave an 8 month old in a bathtub who is extremely mobile and able to move around his own and leave him alone in a bathtub filled with water.. only God knows.

She claims that when she went back into the bathroom that she wasn't able to see my son Landon and began to search. When she pulled him out she tried to preform CPR but was unsuccessful.

Landon's mother continued to provide updates on his condition, and announced that her son had lost his hard fight for life in an update Monday morning.

For those of you who haven't, my little man Landon Chase Rasmussen passed away last night. His body was getting tired and couldn't fight much longer. Landon took his last breath in my arms and is now flying high with the angels.

Police are still investigating the circumstances surrounding Landon's injuries and have not said if the babysitter faces any charges.
