GREENSBORO, N.C. -- It's been 11 days since anyone has seen or heard from Bianca Tanner. The second grade teacher at Reedy Fork disappeared in the middle of the night while visiting her boyfriend in Charlotte.
Police are calling her case a homicide investigation. They haven't made any arrests or named any suspects. While doing interviews, Tanner's 3-year-old son told detectives her boyfriend "hurt mommy in the face."
At the start of the search, investigators said Tanner's boyfriend was cooperating, now they say he's not and has a lawyer. Detectives also say he didn't help in a search over the weekend.
"I know if he was missing and my sister was the last person to see him she would do anything," explains Cerise Richardson, Tanner's sister.
Richardson has her reservations about her sister's boyfriend. She says the two were dating for about six months.
"I'm not sure if he has anything to do with her disappearance, but I do think there is more to the story that he isn't telling us and being forthcoming about."
Richardson has been spending a lot of time with her 3-year-old nephew, Tanner's son.
"Naturally he's used to having his mom so he's wanted her and as each day goes by that want is increasing more and more,” she said.
Tanner's family has been back and forth between Greensboro and Charlotte searching for her and handing out flyers to anyone in the area.
"I'll go to the end of the earth for my sister and I'm not going to stop until I bring her home,” Richardson said.
School officials and community members put up "Bows for Bianca" around benches, trees, and posts outside of Reedy Fork Elementary.
