PLANO (CBSDFW.COM) - As the investigation into a series of rapes in Plano continues, the police department believes they have a new tool in trying to solve the crime.
On Friday the department released a sketch of the suspect. He's accused of four attacks so far in the Collin County area. All of the attacks have had one thing in common - the women in their 50's & 60's are all part of the same sorority, Delta Sigma Theta.
Because the suspect targeted a specific sorority, police held a safety class recently for women from the sorority alumnae group.
Police also have a dna sample of the rapist but so far that has failed to produce an arrest.
The attacks have happened over a one-year period. Plano police say their investigation is ongoing.
If you have any information on the case, they ask you call (972) 941-2148 or Crime Stoppers at (877) 373-8477.
