Maria Rodriquez-Barnes, 30, was charged with first degree premeditated murder after deputies discovered her son dead in the "left rear floorboard" of her Nissan pickup on March 25



A witness, who saw Rodriguez Barnes "rolling from side to side in what appeared to be her blood," called 911, according to an arrest report for Rodriguez- Barnes.


The witness also lifted her shirt and saw blood on her chest and a wound on her back.


Deputies arrived at The Boardwalk on Okaloosa Island’s parking lot around 8:30 a.m., where they discovered Jaxxon Rodriguez-Barnes slumped over a pillow with a gunshot to the chest, said an Okaloosa County Sheriff’s Office press release.


They asked Rodriguez-Barnes if anyone had shot or assaulted her, and she said no. When asked what happened, she said, "I can’t breathe."


The arrest report also said Rodriguez-Barnes was still on scene at the time her baby was found, and she never said anything about him.


Deputies executed a search warrant on the truck and found a 9mm handgun and shell casings.


Inside the vehicle, a handwritten note from Rodriguez-Barnes was also found. The handwritten note included where to find additional documents and other ‘needed information," the arrest report said.


About an hour before the two were found, she sent the pending plans via text and email to family members.


She was booked Tuesday into the Okaloosa County Jail.
