TexasSandman: I do remember the city being gripped by terror when they believed there was a serial killer on the loose. I was around 20 at the time and going to TCU. There were lots of announcements at the school about NOT walking anywhere alone and they beefed up the security at the school big time. There was a run on mace at the stores - I remember it being hard to get because everyone wanted some. One day while driving home from school on Hulen St. I noticed a pickup truck that kept going the same speed as my car. I was driving a Camarro, so I couldn't see the driver as he was driving on my left. The car started squeezing me over, so thinking he was drunk, I speeded up to get away from him but he speeded up, then I slowed down and he slowed down. I speeded up and slowed down twice more trying to evade him with him following suit. As you can imagine, I was getting pretty darn scared, so I floored it and then suddenly hit the brake just in time for him to turn down the road where the synagogue was being built, hitting the front corner of my car with his rear bumper. He attempted to have me follow him down a road where there was construction and vacant lots but no one around. Fortunately, I had sense enough not to follow him. I memorized his license plate number and took note of the fact that although it was a warm sunny spring day he was wearing a hunting hat with earflaps and the kind of coat deer hunters wear. I drove home, making sure he was not following me and called the police - when I told them my story, they put me right through to the serial killer task force and sent detectives out to take a statement from me that day. The damage to my car was pretty slight - he just clipped the front corner so my dad just had it fixed - it cost almost nothing and my dad didn't want the man to learn where I lived. To make a long story short, it was an African American man. It could have been Curtis Brown. I guess I'll never know.
Snowme: I think you are thinking about William Ted Wilhoit who hinted to John Terrell, the PI that he was responsible for Carla's murder. He was parolled in January 2003 after being in Texas Correctional System for 22 years.
One of Carla Walker's relatives has turned up under the name of Mickey on dreamin demon dot com I don't know if I can link to that site here, but there is a thread about Carla Walker. Mickey last posted on April 8, 2009. She is in contact with John Terrell.
