Leo Jacobson was an elderly man whose car was involved in a hit-and-run on Warren Fox in January 2022. Warren forced Ethan Williams to investigate the hit-and-run driver, with Ethan discovering in April that the car used in the hit-and-run belonged to Leo. However, this information was not relayed to Warren as Warren's son Joel Dexter threatened Ethan into keeping quiet. Doing her own investigation in August, Ethan told Sienna Blake about his discovery, so she called Beinheureux Retirement Village pretending to be Leo's granddaughter Janet.
Upon meeting Leo, he immediately realised that Sienna was not Janet, so Sienna quickly lied that she was Janet's primary school friend Jenny. Sienna showed Leo several family photographs to find out if he recognised Warren, to which he did not. Before leaving, Leo told Sienna to send his regards to "Father Dexter", revealing to Sienna that Joel had borrowed his car in January but did not return it.
