DNA, Crime Scene Evidence Pointed to Father in 1981 Child Murders (Arkansas Democrat Gazette – 10/19/2023)
DNA evidence sealed investigators’ conclusion that Weldon Alexander murdered his children in 1981.
Law enforcement officials on Thursday announced that Weldon Alexander is the sole viable suspect in the brutal stabbing murders of Karen Alexander, 14, and Gordon Alexander, 13.
In a news release, Texarkana Arkansas Police Department said recent advancements in DNA processing technology, applied to evidence in the case last tested in 2012, pointed to the teenagers’ father as the culprit.
Retired TAPD Capt. Calvin Seward and state forensic criminologist Dr. Todd Steffy consulted on the case with Kelli Dixon, a DNA scientist at the Arkansas State Crime Lab, according to the release.
Menomonee Falls Cold Cases, DNA Offers Answers Decades Later (FOX6 Milwaukee – 10/20/2023)
Investigators are again looking into two decades-old Menomonee Falls cold cases after DNA has offered answers from beyond the grave.
Detectives stood and watched as workers at Milwaukee‘s Holy Cross pulled a casket from the ground this July. Undisturbed for 15 years, investigators were looking for what was inside: DNA from the body of Clarence Marcus Tappendorf.
Douglas was interviewed by detectives in 1986 during a routine canvass, but at that time, there was no evidence to link him to the murder. Connecting Douglas as a suspect was difficult because Douglas had no criminal history; therefore, his DNA profile was never obtained by law enforcement and was not entered into CODIS. Douglas was 33-years old at the time of Ms. Scalf’s murder. He died in 2008 from natural causes.

San Diego Police Department Teams with Othram to Identify 1973 Homicide Victim (DNASolves – 10/20/2023)
In June 1973, at approximately 11:20 a.m., fishermen found the body of an unidentified female in the San Diego Bay between Laurel Street and the US Coast Guard Station. The woman’s body had been dismembered and placed into an orange suitcase and several plastic bags. An autopsy revealed the individual to be a victim of a homicide. Details of the case were entered into the National Missing and Unidentified Persons System (NamUs) as UP58950.
In 2020, the remains were exhumed by the San Diego County Medical Examiner’s Office to attempt identifying the individual through DNA. With financial assistance from NamUs, a portion of the skeletal remains was sent to Othram, a private, forensic biotechnology company. Othram scientists developed a suitable DNA extract from the highly-degraded remains, recovered a half-century ago. Then, Forensic-Grade Genome Sequencing® was utilized to develop a comprehensive DNA profile. Othram’s in-house forensic genetic genealogy team used the profile to develop investigative leads that were returned to the San Diego Police Department.
With the leads in-hand, San Diego Police investigators were able to eventually identify the unknown homicide victim as Arminda Grangeia Rodrigues da Silva Ribeiro born September 16, 1943 in Portugal. Investigators learned that Ribeiro lived in the Ironbound neighborhood of Newark, NJ, prior to her death. Additionally, she still had family who lived in that area.
