RALEIGH, N.C. — Police released new details Thursday about the stabbing death of a Raleigh woman earlier this week, including information that they are investigating the possibility of a second suspect.

Early Tuesday morning, Raleigh police found 22-year-old Lauren Michele Redman outside her apartment building at 3010 North Walnut Creek Parkway.

Authorities said Thursday that Redman was assaulted in her apartment and apparently crawled out of her front door and into a breezeway, where a neighbor discovered her. She was alive when she was discovered, but died at the scene a short time later, police said.

A man wearing bloody clothing, who police said was observed by witnesses, was the neighbor who found Redman and had administered first aid.

Byron Lamar Waring, 19, was arrested Wednesday and charged with one count of murder in connection with Redman's death. Authorities said the victim knew Waring, but would not say how they knew each other. Police, however, said there was no indication that the death was a result of domestic violence, nor any evidence that the two were intimately involved.

Police also said that there is no connection between Redman's death and a rape reported on Cum Laude Court last week.

Redman was an English major at North Carolina State University, but she had not taken any classes there for more than a year. Her family is planning a memorial service for next Tuesday at East Wake High School, where administrators said she was a standout tennis player.

In a hearing Thursday, Waring was denied bond.
