Investigators tested his clothing and DNA, finding no blood, fingerprints, or DNA linking him to the crime scene, which eliminated him as a suspect.

What forensic evidence linked Sarah Johnson to the murders?

Forensic evidence included high-velocity blood spatter on a pink bathrobe, gloves with Sarah's DNA, gunshot residue on clothing and gloves, and fiber transfer from her T-shirt to the bathrobe.

How did Sarah Johnson attempt to mislead investigators?

She placed knives at the foot of her parents’ bed to suggest a gang-related crime, disposed of a shower cap and gloves to hide evidence, and claimed she was asleep during the murders.

Sarah wanted to continue her relationship with Bruno Santos without interference from her parents, and she aimed to inherit her parents’ assets to secure a life with him.

What role did the bathrobe play in the investigation?

The bathrobe contained hundreds of tiny blood spatter marks from both parents, gunshot residue, and Sarah’s DNA, proving she wore it during the murders and directly linking her to the crime.

How did the investigators confirm Sarah wore the bathrobe over her T-shirt?
