Richland County, SC (WLTX) - Richland County Sheriff Leon Lott said Friday that blood evidence was found in the bedroom of missing teenager Gabbiee Swainson.

Lott made the disclosure at a news conference updating developments in several crimes.

Swainson, 15, hasn't been seen since August 18. Deputies say Freddie Grant, 52, kidnapped the girl early that morning and took her to his home.

The sheriff also said Friday that duct tape with Swainson's hair on it was found in a junk yard near Grant's home in Elgin. Officers said earlier this week that they had been actively searching that area for clues.

According to the sheriff, signals received from Swainson's cell phone showed that her phone traveled from her home to Grant's residence the morning she was reported missing.

Lott says his department still believes the girl is alive, and they are actively looking to find her.

Officers say since they began questioning Grant in the crime, he has been uncooperative in the investigation, referring officers to his public defender.

Thursday, Lott released a photograph of the pajamas they believe Gabbiee may have been wearing when she was taken. He also said Grant was driving a 1992 Ford Escort that was light blue in color, that they think he used when he took the girl. 

Anyone with information about Gabbiee's disappearance or Grant's actions should call Crimestoppers at 1-888-CRIME-SC.
