Several hours later, responders found the body of Sydney Hanson in what’s believed to be her bedroom. She had been stabbed multiple times, and there were materials with accelerant on top of her body.

Sydney Hanson’s coworkers had planned a baby shower for Sydney at 11 a.m. Monday. She never showed up for the shower.

Sydney Hanson had a restraining order against Evans, and Evans was also a suspect in slashing Dwayne Hanson’s tire after a confrontation between the two at the Hansons’ home Oct. 26.
