For the second time in less than a week authorities are waiting on toxicology results to determine what caused the death of a 19-year-old girl with ties to Forsyth County.

Brandy Leigh Hendrix of Charleston Park Road in northeastern Forsyth died Oct. 8 at what authorities say was the home of a friend in Roswell.

Roswell Police Sgt. Bobby Brackett said the department is waiting for test results from the Fulton County Medical Examiner's office.

"They were friends and she met this friend out and because of her condition she went to the friend's house to sleep for the night," he said.

Brackett said he did not know details of Hendrix's condition.

"Our investigation is still ongoing with this," he said. "We're hoping that we're going to get something back from the medical examiner fairly quickly that's going to give us the exact cause of death. When we get that, we will conclude the investigation."

Hendrix's death came four days after the body of 19-year-old Cassondra "Cassie" Ellen Key was found at the northeastern Forsyth County home of a grocery store employee.

According to a Forsyth County Sheriff's Office report, the employee found Key about 3 a.m. Oct. 4 at the store and took her to his house to let her sleep.

He told the investigating deputies she appeared to be intoxicated and he didn't want her to drive. Key lived in Dawson County.

The employee dropped her off at his house and then went back to work. When he returned later that morning, Key was dead.

No charges have been filed in the case. Forsyth County authorities have said they don't suspect foul play, but it could be three months before toxicology results return and her cause of death is determined.

Though the toxicology results are pending, the Roswell police report of Hendrix's death said that drugs may have been involved.

Funeral services for Hendrix, a 2007 North Forsyth High graduate, were Saturday.

According to school's 2007 yearbook, she was a member of the 3.0 Club and Future Business Leaders of America and had been a cheerleader her sophomore year.

Her mother, Martha Hendrix, said Tuesday she does not think there is anything suspicious about her daughter's death and that it was "just an accident."

She said she thinks her daughter had recently met the friends she was with when she died last week.

"She was getting ready to go to college to be a psychiatric nurse," Hendrix said, adding that her daughter was going to start classes at Gainesville State College in December.

Hendrix said her daughter loved animals.

Other survivors include her father, Andy Hendrix of Cumming; brother, Shawn Andrew Hendrix of Gainesville; and three grandparents.
