GARY | Gary police are asking for the public's help in locating a developmentally disabled woman who went missing Saturday with her 2-year-old nephew.

Diamond Bynum, 21, and King Walker, 2, were last seen Saturday morning at their home in the 500 block of Matthews Street in Gary's Brunswick neighborhood, police Lt. Thomas Pawlak said.

Bynum and her step-mother, Susanne Bynum, lied down with King for a nap. When Susanne Bynum awoke about 11 a.m., Diamond Bynum and King were gone.

"They assumed she took her nephew to a local store," Pawlak said. "She had a tendency to do so."

The family reported Diamond Bynum and King missing Saturday afternoon, Pawlak said. Diamond Bynum "has the mental capacity of a 7-year-old," he said.

The family moved to the Gary neighborhood from Hammond in February, and Diamond Bynum was not familiar with the area, said Diamond's father, Eugene Bynum.

King's mother, Ariana Walker, of Chicago, dropped her son off with his grandparents Friday while she attended school and had planned to pick him up Saturday evening, Eugene Bynum said.

"We believe King actually may have opened the door, and Diamond gave chase," he said.

King is much faster than his aunt, and the two may have wandered far enough that Diamond couldn't find her way home, he said.

Police received several reports of the two being sighted in the area, including twice — Saturday and Sunday — at the McDonald's at West Fifth Avenue and Grant Street, Pawlak said.

Eugene Bynum said his family also posted fliers at a local scrap yard after a report that Diamond was spotted there collecting aluminum cans.

"She's very friendly," he said. "I'm not sure why she would do that. I don't know."

Ariana Walker has been out looking for King since he and her sister disappeared and has not returned home, Eugene Bynum said. Family members have printed hundreds of fliers with information about the missing aunt and nephew and posted them throughout the area and inside local businesses.

"I've been the one printing out fliers, and we're out of ink right now," Eugene Bynum said.

Pawlak said Gary police canvassed the neighborhood Monday morning with fliers. The department also shared a copy of the flier on its Facebook page.

Eugene Bynum said employees at McDonald's gave his daughter and grandson free food but didn't call police.

"So the message we're trying to get out is if you see them, call the police," he said.

Pawlak said restaurant workers gave the pair food Saturday, but employees likely didn't know they were missing at that time because they were not yet in the news.

"Hopefully somebody will see this and do the right thing," he said.

Diamond is African-American, 4 feet 8 inches tall, 210 pounds and has gold highlights in her hair. She was wearing a white top and blue jeans, Eugene Bynum said.

King is African-American, 3 feet tall, 35 pounds and has braided hair. He was last seen wearing red shorts and a blue T-shirt. King knows a handful of words but does not speak in sentences, Eugene Bynum said.

Police are asking anyone with information about the pair to contact Detective Nelson Otano at (219) 881-1209. Anyone with information about Diamond and King's whereabouts is asked to call 911.
