People v. Shamblin, 186 Cal. Rptr. 3d 257

Background

In 1980 Elizabeth Crossman (age 67) was found dead at home from manual strangulation with blunt head trauma; semen from her vagina was later DNA-matched to Shelby Glenn Shamblin decades later.
DNA from preserved 1980 vaginal swabs was entered into CODIS after testing in 2002; Shamblin’s DNA submitted in 2010 produced a hit in 2010–2011 leading to his arrest.
At arrest (2011) Shamblin was interviewed after Miranda warnings; he made equivocal references to counsel, later unambiguously requested advice and the interview was terminated.
During booking a deputy asked routine questions; Shamblin volunteered incriminating remarks about leaving DNA and expecting to be caught.
A jury convicted Shamblin of first degree murder (premeditated/deliberate and felony-murder based on rape/attempted rape); he was sentenced to 25 years to life.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency — premeditation/deliberation	Evidence (prolonged manual strangulation, head blows, defensive wounds, bruising near genitals) supports premeditation and deliberation	Strangulation was spontaneous; no evidence of prior reflection	Affirmed — substantial evidence supports premeditation/deliberation (prolonged strangulation provides time for reflection)
Sufficiency — felony murder (rape/attempted rape)	Semen in victim, nudity, thigh/inguinal bruising support rape or attempted rape in continuous transaction with murder	Intercourse occurred postmortem; lack of vaginal injuries and intact clothing show no live sexual assault	Affirmed — substantial evidence supports rape/attempted rape or attempted rape in continuous transaction with murder
Admissibility — statements to detectives (Miranda invocation)	Statements before clear invocation admissible; invocation was ambiguous so questioning until unambiguous request was permissible	Early statement (“I think I probably should change my mind about the lawyer”) was an unequivocal request and later statements should be suppressed	Affirmed — court reasonably found first reference equivocal; clear invocation occurred later, so post‑invocation statements were excluded as ruled and pre‑invocation admissions were admissible
Admissibility — booking statements (booking-question exception)	Routine booking questions and neutral follow-ups permissible; deputy’s questions were non‑interrogative and therefore admissible	Deputy’s questions were a pretext to elicit incriminating statements and required Miranda protection	Affirmed — booking‑question exception applied; deputy’s questions were routine/neutral and responses admissible
Jury question / section 1138 response	Prosecutor: jury needed clarification re first vs second degree given dual theories; court reread instructions	Defendant: court’s response misstated/failed to explain that second degree = murder without premeditation and deliberation; claimed error	Waived and meritless — defense approved the proposed answer; rereading complete instructions was within discretion and harmless even if erroneous
