Hazana was reportedly last seen Sunday morning at Gabbard Park at 1201 Dexter Dr. S.
According to the police department's Facebook post, Hazana's mother said she arrived at the park with her daughter around 8 a.m. She then said she returned to her car to get a bottle for Hazana.
Upon returning from her car, the mother discovered the 2-year-old had vanished from her stroller.
Two fishermen later told police they heard the mom screaming for help.
Hazana is described as a black female, approximately 3' tall and weighing 28 pounds. She has black hair and brown eyes. The 2-year-old was last seen wearing an olive green jacket, with a black "girl squad" shirt, cream-colored pants, dark pink shoes, and a purple beanie.
Police said Hazana also has a dark-colored birthmark around her big toe on her left foot.
Hazana's father, Taboerick Anderson, said Christon started acting strange and avoiding him within the last couple of months.

Anderson said he spoke to Christon briefly after she reported their daughter missing and immediately got a bad feeling.
"Terror, panic, confusion, worry, dread, resentment, just a lot of mixed emotions," Anderson said.
He told ABC13 that Christon lives in Bryan and it's not like her to go to that park, which is usually pretty quiet.
On Sunday, divers with the Harris County Sheriff's Office searched the pond at the park. They also used a drone and dogs to check the woods.
Police stated later Sunday night that the investigation in the park was completed, and officers were expecting to canvass nearby neighborhoods.
The 2-year-old's family also searched and handed out flyers.
"I just want her back. Wherever she's at, I just want her back," said Velt Burns, the girl's aunt.
Christon is being held on a $2,000 bond.
Anyone with information in regards to Hazana's whereabouts is urged to contact police at 979-764-3600.
