5 key details about the murder of Danielle Jennings
1) Danielle Jennings' murder was initially suspected to be a burglary-gone-wrong murder case
As reported by Oxygen, on March 15, 1999, when police officers reached the victim's residence, they found the house completely ransacked. Gwinnett County Police Detective David Henry revealed that the bed was messed up, and one of the dresser drawers was open.
Additionally, Danielle's purse was dumped out, indicating someone threw out its contents. The case was initially considered to be a burglary gone wrong. However, while scrutinizing the crime scene, authorities found no signs of forced entry. Moreover, no valuables in the house had been stolen, indicating it was a premeditated murder.
2) Danielle Jennings died of asphyxiation
As reported by Oxygen, when investigators reached the crime scene, they found that Danielle had a ligature around her neck. Detective David Henry reported that the mark looked like some kind of stocking had been tied around the victim's neck very tightly.
Reportedly, when Danielle's autopsy reports arrived, it was revealed that she died of asphyxiation. Investigators predicted that the killer came up from behind her with a nylon stocking, pulled it tied around the victim's neck until she was unconscious, and then tightened it until Danielle was dead. However, authorities found no defensive injuries.
3) Investigators discovered that Danielle had filed a harassment complaint against a coworker
As reported by Oxygen, on the day of Danielle's disappearance, she went for a lunch break from the office, but did not come back. Reportedly, it was around 11:00 am when Danielle called Luis for lunch, but he couldn't attend.
When Luis called her back in the afternoon, one of her coworkers informed him that she had gone for a lunch break. Luis had a solid alibi, so he was excluded from suspicion. However, during the interrogation, Luis revealed that Danielle had a coworker named Jeff, against whom she had filed a se*ual harassment complaint.
Reportedly, Danielle Jennings informed her office manager that Jeff had been hanging around her desk and made inappropriate comments about her. As reported by Oxygen, when Jeff was interviewed, he confessed to liking her. However, Jeff had a verifiable alibi, which claimed that during the time of the murder, his truck had broken down at a job site. Jeff was also excluded from suspicion.
4) Investigators suspected maintenance man Calvin Oliver to be the killer of Danielle Jennings
As reported by Oxygen, on March 18, 1999, one of Danielle Jennings' neighbours, Miss Kirk, contacted the police and revealed an unusual incident that had taken place a week before the murder.
As per Detective David Henry, Miss Kirk revealed that one morning, she was awakened by someone knocking at her door. She couldn't see anyone when she looked through the peephole. However, minutes later, the front door was knocked again. When it was opened, she saw a maintenance man standing there.
The man claimed that he was there to change the lightbulbs, but stumbled when Miss Kirk said she didn't ask for it. The man left the apartment, saying it was the wrong apartment. As reported by Oxygen, the maintenance worker was eventually tracked down as a man named Calvin Oliver.
It was discovered that Calvin had started working around the neighborhood in September 1998. However, until the time of Danielle's murder, 10 residents reported robbery in their apartments without any signs of forced entry. One resident revealed that the thief claimed to be a maintenance man.
As reported by Oxygen, when Calvin Oliver was brought in for questioning, he denied being part of the robberies. However, while checking Oliver's personal history, it was revealed that his crime records dated back to 1974.

5) Calvin Oliver was convicted of Danielle Jennings' murder by her engagement ring
