PLANO, Texas, Dec. 10 (UPI) -- Police released a composite sketch of a man suspected of breaking into the suburban Dallas homes of four alumni of the same sorority and raping them.
All of the attacks, police said, were on women who had been members of the predominantly African-American Delta Sigma Theta sorority, The Dallas Morning News reported.
The victims, in their mid-50s to mid-60s, were sexually assaulted in the Dallas suburbs of Plano, Coppell and Corinth, CNN reported.
A time line from the Plano police shows the assaults took place between November 2010 and October 2011, the U.S. network said.
Police said they have a DNA profile of the suspect, and have released surveillance video and snapshots from the video.
He is described as a black man in his late 30s to mid-40s, between 5 feet 7 inches and 6 feet tall, and weighing 250 to 300 pounds.
In each assault, the attacker said something that indicated he knew something about the victim, police said.
