GARY, Ind. (CBS) -- A local family is vowing never to stop searching, six years after their two loved ones vanished in Gary, Indiana.
King would now be 8 years old. Investigators last year released an age progression image showing what the boy might have looked like at the age of 7.
On Sunday, King's emotional grandmother spoke out, pleading for more help from police and the public.
"I'm never giving up, but I'm just – my heart, my mind is just – I can't keep going on like this, not having no answers," said La Shann Walker.
Family says Bynum ahs special needs and has the mental capacity of a 5-year-old. She would be 27 today.
