Sabrina Brook Starr, 21, was found shot to death in her Springfield, Missouri, home on November 2, 2018. Investigators tied her killing to a violent incident the day before: on November 1 Luis Perez returned to a residence shared by roommates Steven Marler and Aaron “Joshua” Hampton and opened fire, killing Marler, 38, and Hampton, 23, and seriously injuring two others.

Evidence indicated Starr had given Perez the firearm used in the earlier shootings. Shell casings at Starr’s scene matched those from the November 1 crime scene, and authorities believe Perez killed her to eliminate a witness. Perez was arrested and charged with three counts of first-degree murder and two counts of assault; two others faced related charges, including an accomplice charge and tampering with evidence.

Does anyone have information about Sabrina’s last day or remember her in Springfield that could help fill gaps in the timeline?
