TULSA - On this weekday morning Johnny Hubbard is visiting the place where his life changed forever.
It's the apartment complex where his son disappeared.
"I knocked on doors for weeks out here," said Johnny.
Just a few days after Christmas,18-year-old Khyre Campbell left an apartment near 23rd and Jackson in west Tulsa and told his girlfriend he'd be right back.
Six months later, he still hasn't come home.
"Some days are better than others," said Johnny. "Some days I wake up very emotional and some I kind of get by. But he's always on mind. Every day."
He's spent many days after Khyre's disappearance knocking on doors and posting fliers all over west Tulsa.
But they haven't produced any real clues.
Johnny believes his son fell into the wrong crowd.
"He was out there and he had some people who didn't like him and some people who were afraid of him," said Johnny. "I don't know. He was a little guy so he had a little man's complex. He had to be tough."
"We've received some tips," said Jill Roberson with Tulsa police. "And detectives are following up on that but we haven't been able to connect any dots."
Khyre last used his phone about three hours after he vanished. And now that six months have passed, Johnny believes his son is likely dead.
"I would always like to keep that ounce of hope but knowing my son, I don't think so," said Johnny.
Now, his family only wants a simple question answered.
