HOUSTON, Texas (CNN) -- An attorney for Charles Victor Thompson described the escaped death-row inmate on Saturday as "charming, articulate and well-spoken," and said it's doubtful that the convicted murderer would kill again.A nationwide manhunt continued for Thompson, 35, who brazenly walked out of Harris County Jail unhindered on Thursday after meeting with an attorney, escaping from handcuffs, changing into street clothes and flashing a fake ID badge.The U.S. Marshals Service has offered a $10,000 reward for information leading to his capture.Authorities have acknowledged that a series of mistakes led to Thompson's escape. They're investigating the lapses and whether someone inside the jail helped him. "Mr. Thompson is a charming, articulate, well-spoken young man, and he's very intelligent," his attorney Terry Gaiser said Saturday. "I'm sure he's very capable of doing all of this on his own, without any help from anyone.""He's the kind of guy that makes friends wherever he goes. All his life he's been described as being a charming fellow, so it wouldn't surprise me if he didn't make friends with the deputies."Thompson escaped while temporarily housed at the jail for an October 28 resentencing hearing, during which he was sentenced to death for a second time. The Texas Court of Criminal Appeals ordered the resentencing, contending Thompson's right to counsel was violated during his trial.Authorities believe Thompson smuggled the clothes he wore at his hearing back to his cell, and used them in his escape. He was last seen wearing a dark blue shirt, khaki pants and white tennis shoes.Thompson was convicted of capital murder in April 1999 in the shooting deaths of his former girlfriend, Dennise Hayslip, 39, and her friend, Darren Cain, 30.Gaiser said he wasn't the attorney who met with Thompson before his escape. Authorities have not identified who the visitor was. Gaiser said he hadn't seen his client since the hearing.Gaiser said Thompson didn't necessarily need inside help to escape, because he has been incarcerated there twice: once for his trial in 1998-99, and this time since May."I'm sure he knew all the procedures, having been in there for the length of time that he was," Gaiser said.Gaiser downplayed reports that Thompson had made up a "hit list" in jail that included the relatives of his ex-girlfriend and jurors.Hayslip's mother, Wynona Donaghy of Tomball, Texas, and other relatives of the victims have gone into hiding.Gaiser said Thompson was found with a list seven years ago, but has behaved well in prison, with no disciplinary reports filed against him since then."I don't believe that Charles is going to kill anybody again," Gaiser said. "He's dangerous, obviously, if placed in a desperate situation."However, on Thursday, Donaghy told reporters, "He can make people believe he is the most innocent man in the world.""He is a threat, not only to himself, but to anybody around him," she said. "I believe he'd come after anybody."CNN's Keith Oppenheim contributed to this report.Copyright 2005 CNN.
