Authorities have used DNA technology to make an arrest in a nearly decade-old series of Sacramento-area rapes.

Prosecutors on Friday said the man nicknamed the "roaming rapist" attacked 10 women throughout Sacramento County from 1998 to 2003. His victims ranged in age from 14 to 42.

Investigators had trouble linking the attacks because the rapist stuck to no particular pattern.

They collected DNA samples from victims but were unable to find a match until last week. That's when a state crime lab used updated technology to find a general match to the suspect's brother, a convicted felon awaiting trial on sexual assault charges.

Investigators then were able to zero in on the suspect, 39-year-old Dereck Sanders of Isleton, a delta town south of Sacramento.

He was arrested late Thursday and faces 35 counts.
