A police spokesman said there was no other new information about the crime.
Taft, 62, was found assaulted at the home of a friend at 2710 Cartier Drive Saturday, March 6. Detectives say they believe the attack happened either late Friday night or early Saturday morning.
Police have released practically no information about the case, and even got a judge's order to seal search warrants and 911 calls made after the attack saying that making the material public could harm their case.
A person with knowledge of what happened told ABC11 that Taft's sister called paramedics Saturday morning after realizing something was wrong.
She thought her sister was experiencing a complication from a medical procedure Taft had undergone the day before. However, when Taft arrived at WakeMed and was examined by the doctor who performed the procedure, the physician reportedly realized she had been assaulted.
Taft reportedly suffered trauma to her head. That's when police were notified.
She died from her injuries three days after arriving at the hospital.
The Taft family is offering a $25,000 reward for anyone who provides information leading to the arrest and conviction of the perpetrator of the crime. Anyone with information that might help police detectives is asked to call Raleigh Crime Stoppers at 919-834-HELP.
