“A roadside strangler confounds California detectives in this tense and gritty true-crime account from Bruce Henderson ( #1 New York Times bestseller And the Sea Will Tell). With novelistic urgency, Henderson tells two equally chilling stories in Trace Evidence: The Hunt for the I-5 Serial Killer: how a handful of detectives and a trace-evidence expert nabbed the killer and how a police detective’s brother and ‘somebody’s husband’ became that killer.” Publishers Weekly
