DALLAS At a Monday night news conference, Dallas police said serial rape suspect Van Dixson has now been linked by DNA tests to four of the nine South Dallas sexual assault cases.
Dixson, who remains at large, now has four felony arrest warrants; additional lab results are pending from two cases. There was no DNA evidence available for three of the crimes.
The suspect provided a DNA sample during questioning last Wednesday before he was named as a suspect, police spokesman Maj. Jeff Cotner said.
'He allowed us to search his house and vehicle, and the suspect was released at that time,' Cotner said. 'We had no charges on him.'
The next day, September 5, Cotner said Dixson was seen on video surveillance walking away from his Saturn vehicle at a McDonald's restaurant in Garland.
He disappeared before detectives got their first DNA match.
After finding Dixson's car, police searched his home again.
Cotner said detectives have interviewed friends and associates, adding that the department is being very aggressive in trying to track down the suspect.
'We're doing everything possible to determine his whereabouts,' Cotner said.
Police describe Dixson as black, 5'-7' tall, 181 lbs., with black hair and brown eyes.
Crime Stoppers has a $5,000 reward for information leading to Dixson's arrest and indictment. Oak Farms Dairy has offered an additional $10,000 in reward money. Call 911 if you have any information.
Cotner also said that Alan Mason, who was named last week as a 'person of interest' in the serial rape case, has provided a DNA sample which will be used to see if the results will clear him from further investigation.
Hours earlier, Mason questioned why police publicly identified him without having the evidence to consider him as a suspect. Mason is in jail for violating the terms of his probation for a DWI conviction.
