On Friday, Taylen’s body was retrieved from the mouth of an alligator.
AGoFundMeorganized to help offset funeral costs for the victims described Jeffrey as a single mom who worked at CVS and was “dedicated” to making “a better life for her son.”
“Taylen was a sweet and happy toddler and loved his mom. During Pashun’s work breaks, she would FaceTime so that she could spend every moment possible with him. During the day, Taylen would grab anyone’s phone and pretend to call his mom. To see them together and their love for each other was a blessing,” the fundraiser description reads.
Mosley is scheduled to appear in court April 11.
