Lt. Terry Hastings told The Associated Press on Friday that detectives interviewed Curtis Lavelle Vance at his home in Marianna and collected forensic evidence in the death of Anne Pressly.
Hastings said the case against Vance "was made off of forensics." Hastings declined to say how they obtained the evidence - whether it willing given by Vance or taken without his knowledge. In Arkansas, police can obtain evidence from discarded material or trash - DNA evidence from a cigarette butt, for example - without a warrant.
Deputy prosecutor John Hout said the evidence found in the victim's home tied Vance to the killing. Hout wouldn't specify whether it was DNA evidence or other material.
Vance, 28, was arrested without incident Wednesday night on suspicion of capital murder in the Oct. 20 attack on Pressly, 26, a morning anchorwoman for Little Rock's ABC affiliate, KATV. She died five days later, having never regained consciousness.
Tips from the public led to the arrest within a couple of hours after police publicly named Vance and his picture was broadcast on television. Vance was arrested at a home in central Little Rock, which is some 90 miles from Marianna, where he lives.
At a closed court hearing Friday, Judge Lee Munson ordered Vance held without bond. Hout said Vance said nothing during the short hearing, which was held inside the Pulaski County jail because courts were closed Friday. Hout said Vance did not enter a plea.
Earlier, Hastings, said he did not know if Vance had an attorney. He said a public defender would likely be appointed.
Valerie Cooper, the mother of Vance's girlfriend, Sheanika Cooper, told KATV that she learned of the charge Thursday morning and doesn't believe Vance committed the crime. She said he has "a real nice personality."
"He didn't give me no kind of hint or nothing. It shocked me," she said. "I don't want to believe he did something like that."
When police announced Wednesday that they were looking for Vance, they had said he might be with Sheanika Cooper and three children. But they was not with him when he was arrested later that day.
Police did not disclose what led them to suspect Vance in the first place.
Hastings had said previously that DNA and other evidence from the scene gave police a portrait of the person they were looking for, though they did not have a name until this month.
One of Pressly's credit cards was used at a gas station after the beating, but Hastings said security camera footage didn't provide a good look at the person using it.
Asked if Vance had made a formal statement after his arrest, Hastings said: "He talked with detectives. I'll leave it at that."
Pressly's father, Guy Cannady, attended the news conference where Vance's picture was distributed by police.
"It's very difficult to look at the picture, just knowing what Anne went through, that that was the last guy that Anne saw in her life," he said before Vance's arrest.
Pressly's mother found Pressly early on the morning of Oct. 20. She had checked on her daughter after she didn't answer her daily wake-up call.
Pressly appeared briefly in the Oliver Stone movie "W" as a conservative commentator who speaks favorably of Bush's "Mission Accomplished" event on an aircraft carrier after the start of the Iraq war. She got the part when she was noticed by a casting director as she did a news story on the film while it was being shot in Shreveport, La.
