The tragic death of Tyresa Mack proved to be just the tip of the iceberg for authorities on "Blood, Lies & Alibis" (Mon., 8 p.m. ET on ID). The true crime series followed the investigation as the revelation came to light that Mack was but one of a string of victims leading back to the same culprit.
All were young African-American women and all were found strangled in their homes. Mack's sister talked about the moment when she knew something was wrong. It was when Tyresa didn't show up to pick her kids up from school.
"When it comes to the kids, she didn’t play,” she said.
But while police were able to link several killings to the same person via DNA, it wasn't until years later that they were able to link that DNA to a killer. Paul Durousseau was a cab driver who "thrived on meeting young women," according to his brother.
He was convicted of Mack's murder in 2007 and has been charged with five others. He is currently on death row in Florida.
