(NBC) -- Dallas police are searching for a neighborhood watch member they have tied to at least one rape in what police believe are a string of connected sexual assaults in South Dallas.

On Saturday, police identified 38-year-old Van Dralan Dixson as a suspect in connection with one of nine sexual assaults in South Dallas, saying there was a DNA match from one of the cases.

Police did not say how they got a sample of Dixson's DNA.

Maj. Jeff Cotner, with the Dallas Police Department, said investigators are awaiting more laboratory tests to come back on the other assaults. So far, Dixson is only officially linked to the one assault, though police would not specify which case.

Police are now searching for Dixson, having found his vehicle abandoned in a parking lot in Garland on Sunday. Investigators are asking for the public's assistance should anyone see him or know where he may be located.

Police said Dixson is black, 5 feet 7 inches tall and weighs about 185 pounds.

An arrest warrant for aggravated sexual assault has been issued for Dixson. That warrant carries with it a $1 million bond. Anyone who knows Dixson's whereabouts is urged to contact Dallas police.

Cotner said that even though a suspect has been identified, they continue to investigate all leads in the string of sexual assaults.

Dixson's Criminal History

Dixson has an extensive criminal record, including an arrest by Dallas police in early August for deadly conduct, court records show.

Sources familiar with his criminal record told NBC 5 that Dixson was arrested for deadly conduct for pointing a gun at someone four weeks ago.

NBC 5 has learned, at the time, Dixson used an address on Oberlin Drive, though neighbors said he hasn't lived at that address for at least two years.

"He is still getting mail here, from lawyers," explained David Lewis, who now lives at the home Dixson was using as a home address. "My girlfriend was sending it back to return to sender."

Organizers confirmed Dixson was part of a neighborhood crime watch. The Mill City Community Association said Dixson's duty was to inform other participants of future meetings.
