And on that note.... "An armed serial rapist that struck in Dallas three times in the last two months has been linked to similar crimes in Bossier, Louisiana, authorities in both cities say. The perpetrator committed sexual assaults on September 12 and 19, within 1 mile of each other, and assaulted another woman October 30, said Deputy Chief Thomas Castro with the Dallas Police Department. Police have released a sketch of the suspect and say they're looking for a black man, 16 to 19 years old, standing roughly 5 feet 8 inches tall. He has a thin build, police say. The crimes fit the pattern of a rapist accused of inflicting similar attacks in March and May in Bossier, located just outside Shreveport, near Louisiana's northwest border with Texas, he said. Detectives say there are numerous similarities between the Dallas and Louisiana crimes, Castro said. The suspect usually knocks on the door, asking for work or money, before forcing his way into the home, Castro said. He then brandishes a weapon, sexually assaults his victim and flees" So it you leave a female behind as you go to work, make sure they don't open the door or at least get them a gun and teach them how to use it.
