64 year old Velma Nesset set out on April 19^th, 1982, at 4:30 a.m. to walk to her job as a cleaning lady at the Permian Mall in Odessa, TX.  When she did not show up for work, people looked for her, and then called the police. Velma’s partially undressed body was found in a drainage culvert under the mall parking lot.  She had been stabbed, bludgeoned and raped.  The logical suspect, a mentally challenged man who worked at the mall, was tried for her murder. But after that, her case went cold.  A Texas Ranger reinvestigation in the mid 2000s isolated a male DNA profile, but the offender was not in CODIS.  When he was finally named through IGG, police tracked the man down, and he had quite a story to tell them.  According to him, he did not act alone.

On October 5th, 2003, a maintenance worker at at the Country Hills Apartment complex in Rancho San Diego, made a horrific discovery in a dumpster when he found a set of severed legs. It was just the beginning of a shocking and perplexing mystery. The legs were found to have come from an adult woman who was deemed to be a homicide victim. Although police did not find any more of her remains, they did find an important clue; the military-style bag that had held her legs was also recovered, and years later, it would lead to the woman's killer.

In mid 1990s Grand Rapids, Michigan, someone was killing sex workers. Sharon Hammack, a mother of two, was hogtied, stabbed, strangled, raped, and dumped on the side of a road.  Despite many suspects, her case remained unsolved; all investigators had to go on was semen left behind by Sharon’s killer. A DNA profile from the semen was entered into CODIS, and while it did not identify Sharon’s killer…it connected her case to a murder 10 years later, in which Dusty Shuck was stabbed and dumped on the side of a road.  It would take IGG to figure out who the common thread was in the two cases… and  it did so just in time.
