After a brief standoff Tuesday, Mobile Police arrested a suspect in the 1980 cold case murder of Sandra Cassady Williams, who was found dead in Toulminville exactly 39 years ago Wednesday.
According to investigators with Alabama Attorney General Steve Marshall’s office, Williams’ body was discovered in a cul-de-sac on Clemente Court around 9 a.m. on the morning of Sept. 11, 1980. At the time, police indicated Williams had been raped and then stabbed to death. The location where the body was found was several miles from where Williams’ apartment was at the time, which police say was on Azalea Road.
For years, no suspect was identified in the case, but state investigators redoubled their efforts to solve the cold case a little more than two year ago — vowing to retest DNA evidence with new technology and make attempts to track down and interview potential witnesses in the case again.
However, police confirmed to Lagniappe that 61-year-old Alvin Ray Allen’s alleged involvement as a suspect was not determined on the results of DNA testing or the testing of any backlogged sexual assault kit.
Whatever was discovered, though, it was enough to convice a Mobile County grand jury to indict Allen on a single murder charge earlier this year. Allen was taken into custody by police on Sept. 10 after investigators executed an arrest warrant at his home on West Cheshire Drive.
The Mobile Police Department (MPD) SWAT team had to be called the scene after Allen barricaded himself and his wife inside of the home. Allen’s wife eventually left voluntarily and Allen ultimately surrendered peacefully to SWAT officers after they kicked in the front door of the home. He was then taken to Mobile Metro Jail without incident.
Jail and court records indicate Allen does have a history of local arrests, some of which involved violent offenses. He has previous charges for DUI, disorderly conduct, resisting arrest and assault, among other offenses. With his arrest on Sept. 10, murder has now been added to that list.
Allen did not speak to local reporters as he was being transported to Mobile Metro Jail after being questioned by officers at MPD’s police headquarters.
