About

Garcia was tried jointly with Katherine Magbanua in 2019 on charges arising from Dan Markel's killing. The State alleged that Magbanua solicited Garcia, who recruited Luis Rivera, and relied on phone, location, rental, surveillance, financial, ballistic, and fingerprint evidence; Garcia's defense challenged Rivera's credibility and argued that the remaining evidence did not adequately corroborate his account. Garcia elected not to testify, and the jury convicted him of first-degree murder and conspiracy to commit first-degree murder while finding him not guilty on Count 3. In later proceedings, Rivera testified that Garcia brought him into the plan, traveled with him to Tallahassee, shot Markel, and shared cash delivered by Magbanua. Investigators and other witnesses addressed rental, vehicle, phone, location, payment, and recorded evidence concerning Garcia, while the defenses disputed what that evidence established about Magbanua, Charlie Adelson, and Donna Adelson. Garcia did not testify live in Charlie Adelson's or Donna Adelson's trials, although his recorded voice was presented during the former.

GMGarcia–MagbanuaSep 26, 2019 – Oct 11, 2019

Sigfredo Garcia was tried jointly under a State theory that he recruited Luis Rivera to carry out Dan Markel's killing, while his defense argued that Rivera's plea benefits and changing accounts left reasonable doubt. On Day 11, the jury found Garcia guilty of first-degree murder and conspiracy and not guilty on Count 3, with all jurors confirming the verdict when polled.
