Saam Zangeneh led Sigfredo Garcia's defense by challenging Luis Rivera's account and the prosecution's efforts to corroborate it through surveillance, vehicle, phone, financial, and forensic evidence. He presented defense testimony on traffic-stop and digital-record limits, then argued that the remaining gaps required acquittal on reasonable-doubt grounds. The jury convicted Garcia of murder and conspiracy but acquitted him on solicitation.

About
Saam Zangeneh led Sigfredo Garcia's defense and framed the dispute from opening around Luis Rivera's changing accounts, criminal history, and benefits from cooperation. Rather than accepting the prosecution's chain of corroboration, he repeatedly asked whether each source actually identified Garcia or independently established the State's inferences.
During Rivera's cross-examination, Zangeneh tested his gang ties, prior statements, memory, literacy, and cooperation incentives. The court limited several lines of inquiry, established a procedure for refreshing Rivera's recollection outside the jury's presence, and admitted two defense letters while limiting other proposed impeachment. Zangeneh later questioned FBI agent Patrick Sanford about investigative follow-up, unsuccessful gun searches, and Rivera's account; Sanford confirmed that Rivera was the only person who identified Garcia as the shooter.
His other cross-examinations focused on limits in observation and physical reconstruction. James Geiger could not identify the departing vehicle's occupants or driver, David Sims could not determine Markel's movements before officers arrived, and Joanne Maltese confirmed that several garage items were not forensically examined. Zangeneh also challenged Robert Shawn Yao's conditional taller-shooter opinion. The court permitted the testimony after a defense deposition, and cross-examination established that the physical evidence alone did not permit a trajectory analysis and that changed assumptions could affect the opinion. He also questioned the visibility and annotation of bus footage; the court reserved a discovery objection and later admitted the unannotated original after defense voir dire.
On the vehicle and records evidence, Zangeneh questioned investigators about Prius identification, rental and phone-record gaps, repeat-rental inquiries, and the scope of vehicle inspections. His questioning of Christopher Corbitt and Mary Hull tested cell-site precision, handset attribution, missing records, and the limited scope of financial review. In voir dire of Sanford, he examined how Sanford prepared a transcript from noisy audio and elicited that Sanford was unaware of peer-reviewed studies or comparisons with other technology.
During the defense case, Zangeneh examined Stephen Downing about Rivera's traffic stop and the citation's default passenger entry, then used John Sawicki's digital-forensics testimony to develop limits in iCloud, call-detail, and cell-tower evidence. He also cross-examined Katherine Magbanua about Garcia's relationship with Charlie Adelson, Rivera's criminal reputation, and the advance planning of Garcia's family trip. In closing, Zangeneh returned to Rivera's credibility, disputed the claimed corroboration from surveillance, vehicle, phone, financial, and ballistic evidence, offered alternative explanations for the trips and other evidence, and urged acquittal because the prosecution had not proved Garcia's guilt beyond a reasonable doubt.
The jury convicted Garcia of first-degree murder and conspiracy to commit first-degree murder but found him not guilty of solicitation. All 12 jurors confirmed the verdict when polled.
