Dateline: Bad Blood - 5 harrowing details about the murder of Georgia resident Jarmecca “Nikki” Whitehead, revealed

Dateline: Bad Blood covers the cold-blooded killing of Jarmecca "Nikki" Whitehead, a 34-year-old mother who was brutally murdered in her house in Conyers, Georgia, on January 13, 2010. This is perhaps one of the most haunting ones. Dateline: Bad Blood, an NBC true-crime series, goes into the gruesome killing in detail, revealing horrifying shocks and unpicking the bizarre relationships that led to Nikki's tragic death. The series anatomically examines the twisted and sinister route that led to this brutal crime, leaving audiences stunned at the gruesome reality.

What is most disturbing about this case is that the crime was not committed by some stranger who broke into her house but by those people who are nearest and dearest to Nikki—her 16-year-old identical twin daughters, Jasmiyah and Tasmiyah Whitehead. Dateline sheds light on increasing tensions in the home, the violent outbursts, and the critical evidence that ultimately broke a chilling murder.

Here are five frightening facts from the show that reveal the horrific depth of this tragic case.

1. A Torn Family Severed by Custody Fights

As featured in Dateline: Bad Blood, twin sisters Jasmiyah and Tasmiyah experienced an unruly childhood. For most of their growing years, the twin sisters grew up with their great-grandmother, Della Frazier, who provided what appeared to be a stable, healthy home environment. But things unraveled virtually instantly when Nikki recaptured the daughters in the daughters' late teen years. The transition, however, was not smooth for the twins because they resented their mother's strictness and her trying to discipline them. What was initially rebellious behavior eventually reached violent confrontations, laying out the ground for a tragic fate.

Nikki struggled to keep them in check, frequently disagreeing with her daughters over curfews, homework, and their growing disrespect. Their promising future—marked by good grades and after-school activities—unraveled as they grew more violent. Family intervention and court action did little to mend their relationship, leaving a volatile household on the brink of disaster.

2. Repeated Episodes of Domestic Violence

As the tensions mounted, the Whitehead household was a battleground. Police were repeatedly called to the home to separate fights between Nikki and her twins. The twins were said to have physically assaulted their mother on multiple occasions, leading to court-ordered interventions. Nikki, trying to establish normalcy, tried to establish boundaries, but the aggression grew worse.

Juvenile court authorities put the twins in a behavior program at one time to stem their violent behavior. But their anger against their mother continued to intensify. Testimony from witnesses who were friends and family members indicates that Jasmiyah and Tasmiyah did not see Nikki as a mother but as an enemy—one they felt they had to defeat, not obey.

3. The Gruesome Crime Scene That Shocked Investigators

On January 13, 2010, police came to Nikki Whitehead's residence in Conyers, Georgia, with a horrific discovery. Nikki was found dead in the bathroom, her body covered with stab wounds and deep gashes. Her blood was everywhere in the house, the aftermath of a terror-filled and bloody fight.

At first, the twins told police that they returned from school to discover their mother deceased. They acted the grieving role to the letter, weeping and recounting their so-called find in gruesome detail. However, inconsistencies in their account soon alerted people to something being amiss. The girls had scratches and bite wounds on them, which suggested a fight. Forensic examination later revealed that this was no spontaneous attack—this was personal, vicious, and targeted.

4. The Incriminatory Evidence That Revealed the Truth

Despite their initial denial, mounting evidence pointed directly to Jasmiyah and Tasmiyah. Blood evidence took them to the scene of the crime, and their wounds indicated they had defended themselves from a violent attack. DNA testing showed Nikki had fought for her life, biting one of the girls in the altercation. Their alibi fell apart when questioned, and their lies only served to make them guiltier.

The twins' actions following the murder also raised eyebrows. Security cameras recorded them walking innocently into a convenience store shortly after the murder to get snacks, as if nothing had happened. Their carefree demeanor and conflicting accounts of what they were doing when the crime was being committed convinced the police to lean in harder, eventually cracking them.

5. The Dumbfounding Confession and Conviction

As shown in Dateline, after months of denial, Jasmiyah and Tasmiyah eventually admitted it in 2014. What occurred on the evening their mother was killed was appalling and tragic, they admitted under their account. According to what they described, a furious row erupted when there was a fierce argument, and the three of them were engaged in a vicious fight. The twins overpowered Nikki, stabbing her multiple times and beating her in a rage.

With no means of escape from the mountain of evidence against them, both sisters entered a plea of guilty to voluntary manslaughter. They each received a 30-year prison sentence, a bleak conclusion to a case that shocked the country. Their testimony, uncovered in Dateline: Bad Blood, was a chilling description of a family feud that spiraled out of control and ended in an unthinkable slight.
