Abigail was found burned to death in a beauty salon on a deck chair during a beauty appointment (with a hole showing her exposed rib cage). After Grace and the player finished investigating the murder scene, they did not hesitate to send the victim's body to Nathan for autopsy. Nathan found out that the fatal burn wounds were inflicted by a laser of some sort and he said that it was aimed at Abigail's heart. Nathan also passed Abigail's body under his UV scanner and detected a blurry hand print on her arm. The hand print was blurry because it was coated in talcum powder. This prevented Nathan from isolating any fingerprints, but he confirmed that the killer was in contact with talc.
Killer and motives
The killer turned out to be Abigail's best friend Sabrina Kingston.
Sabrina testified that she believed she was on drugs because Veronica Johnson sold them to her, though Grace countered that the "drugs" Veronica sold were actually a mixture of caffeine and talc. Sabrina needed Abigail's help to give her a urine sample as all top colleges (including Harvard and the University of Grimsborough) enforced applicant drug tests and Sabrina was afraid of having her test come up positive albeit Abigail refused to help and for this reason, Sabrina got mad.
During a beauty appointment of Abigail's, Sabrina crept into the treatment room to intimidate her by pointing a hair removal laser on her and thought that if she threatened to kill Abigail, she would give her a urine sample for her to pass the university's drugs checking mechanism. But accidentally, the hair removal laser fired a laser beam at Abigail's chest by itself thus burning a hole through Abigail's chest, which contributed to the murder being linked to a crumpled friendship due to excessive differences.
In the court, Sabrina pleaded guilty to first-degree murder and claimed to have lost herself, but Judge Hall countered that there was nothing worth killing a friendship over. Sabrina was sentenced to 20 years in jail with a chance for parole in 10 years, and although she was not told that she would be tried as an adult, the sentence Sabrina had to serve made it obvious that she was tried as an adult.
