DEKALB COUNTY, Ga. -- DeKalb County police said a deaf man stabbed his neighbor -- a deaf woman -- to death. But the woman’s twin sister said she thinks police have the wrong man.

Just as family members of Tekelia Blackshear came together to remember her, news came of an arrest in the killing. Raw emotion poured out of Blackshear's twin sister LeQuita.

"That was my other half, my twin sister, that's my other half, he just took half of me, you know what I mean? I have to deal with this for the rest of my life. That was my other half right there, I was the closest thing she had,” said LeQuita Blackshear.

Police said her next door neighbor, Darell Smith, also deaf, stabbed the 21-year-old Georgia Perimeter College student to death. A neighbor discovered her body inside her own apartment on Sunday. Sources told Channel 2 that Tekelia was wearing fake handcuffs that appeared to be broken.

The news came as a surprise to family members, who said she had no enemies.

"It was shocking, more than anything, we (were) shocked,” said the victim’s cousin, Anthony Berry. "We never know who our friends are. That’s why we depend on God as our friend, as our savior."

But Tekelia Blackshear's sister doesn't believe Smith killed her twin sister.

"He loved her man, that man loved her. Like that was his sister, man. That man has been around for I don't know how long. He's been in the family for I don't know how long. He did not do that, he did not do that,” said LeQuita Blackshear.

Smith is being held in DeKalb County jail without bond.

The funeral will be held for Tekelia Blackshear will be held Saturday Oct. 10 at 11 a.m. at the Donald Trimble Mortuary on 2nd Avenue in Decatur.
