Ashley Britt McArthur murdered her friend, 33-year-old private investigator Taylor Wright, near Pensacola, Florida, in September 2017 after Wright sought the return of $34,000 she had entrusted to her for safekeeping.

Cell-phone records, financial evidence and surveillance footage helped investigators reconstruct McArthur's movements. She was convicted of first-degree premeditated murder in August 2019 and sentenced to life imprisonment with a mandatory minimum of 25 years.
