DALLAS -- A man who's now connected to at least six sexual assaults in Dallas is currently sitting in a jail cell.

It's all because a lab in Carrollton is hard at work processing over 4,000 rape kits collected by Dallas PD from 1996-2011.  Until recently, those rape kits sat in a warehouse, untested.

The testing started in October, and DNA evidence has been coming back.

DPD says four of those kits - collected back in 2009 - contain DNA that matches 41-year-old Joseph Beaty of Irving.  They also say he's a possible suspect in two 2014 sexual assaults.

Of those six cases, authorities only have enough to prosecute one so far, but they're investigating them all.  That process involves contacting victims who've waited years without arrests or answers.

Major Jeff Cotner, who commands the Violent Crimes Section of the Crimes Against Persons Division of the DPD, told NewsFix that his officers have been receiving additional training and working with victim's advocates and councilors in order to better deal with sensitive investigations.

As the police continue to build cases against rape suspects, District Attorney Susan Hawk has her upgraded sexual assault unit ready to prosecute the influx of cases, and to make sure justice is served.  "Because," said Hawk, "they've waited a long time for their case to be heard."
