What happened in the grocery store attack involving Bianca Ellis?

Bianca Ellis is accused of a fatal stabbing of 3-year-old Julian Wood in a grocery store parking lot. Surveillance footage shows Ellis stealing two knives from a nearby thrift store before the attack. After obtaining the weapons, she spotted Julian and his mother at the grocery store and followed them outside to the parking lot. The attack was particularly horrific, as Ellis allegedly stabbed the toddler in the face and back, while also wounding his mother in the shoulder. The premeditated nature of the crime is evident from her acquisition of the weapons before targeting the victims.
