IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

SECOND APPELLATE DISTRICT

DIVISION EIGHT

THE PEOPLE, B344304

Plaintiff and Respondent, Los Angeles County Super. Ct. No. MA085403

v.

SANTIAGO MARTINEZ et al.,

Defendants and Appellants.

APPEAL from a judgment of the Superior Court of Los Angeles County, Emily J. Cole, Judge. Affirmed as modified.

Sally Patrone, under appointment by the Court of Appeal, for Defendant and Appellant Santiago Martinez.

Micah Reyner, under appointment by the Court of Appeal, for Defendant and Appellant Alberto Mejia.

Rob Bonta, Attorney General, Charles C. Ragland, Chief Assistant Attorney General, Susan Sullivan Pithey, Assistant Attorney General, Idan Ivri and Nikhil Cooper, Deputy Attorneys General, for Plaintiff and Respondent.

Inmates Santiago Martinez and Alberto Mejia attacked another inmate. Martinez and Mejia challenge their convictions for attempted murder and other charges. We agree with the prosecution that we must reverse Mejia’s conviction under section 4501, subdivision (a) because it duplicates his conviction under section 4500. We otherwise affirm. Statutory citations are to the Penal Code.

I

Martinez and Mejia were inmates at a maximum-security prison in Los Angeles County. Within the prison, they were housed in administrative segregation, “a prison within a prison” for inmates who commit violent crimes in prison or who pose other safety concerns. Inmates in this section are cuffed at the hands and ankles with a waist chain anytime they are out of their cells, unless they are in the shower or yard. Zapatistas and 2-5ers are two rival groups present at the prison.

Martinez and Mejia were sitting next to each other at a group therapy session. An officer escorted fellow inmate Gabriel Vildasola past the window of the room in which the therapy session was occurring. Martinez and Mejia used a handmade key to unlock their shackles within seconds. Martinez passed a weapon to Mejia. Officers later found handcuff keys on the floor of the classroom.

Vildasola pulled away from the officer escorting him and began running. Mejia ran out the door of the therapy room with a weapon in his hand and down a hallway parallel to the one Vildasola was running down. A door connected the two hallways. Mejia slipped before reaching the connecting door, and officers pinned him down.

Martinez ran down the same hallway Vildasola took. An officer kicked Martinez’s legs out from under him, causing him to fall to the ground. Martinez got up, shoved past another officer who pepper sprayed him, and caught Vildasola, whom he stabbed four times. An officer jumped on Martinez, grabbing him around the neck, and pulled him off Vildasola, before pinning Martinez to the ground. Martinez had a knife-like weapon in his hand. As officers escorted him away, Martinez yelled, “I got that fool,” so other inmates could hear. He also said, “I stabbed a Zapatista right now,” and, in Spanish, “I’m here for 2-5.” He later told an officer, “This was nothing personal. It’s just business.” During his closing, the prosecutor pointed out a 2-5er tattoo on Martinez’s cheek.

Officers found another handcuff key and weapon in Martinez’s cell.

An officer pinned Vildasola down after the attack when he reached for a weapon on the ground by his hand. The stab wounds to Vildasola’s back and abdomen caused his lung to collapse.

Attorney Robert Haberer represented Martinez, and attorney James Pinchak represented Mejia. During voir dire but before jury selection, the trial court spoke with counsel on the record about safety measures without Martinez or Mejia present. The court noted that earlier, off the record, each defense counsel had requested the court place his clients in a stealth belt due to counsel’s concern for his own safety. The court further noted that it would not have required the belts absent counsels’ request because the court had not noticed any concerns. Due to Pinchak’s earlier on the record objection, the court pulled the prison reports for Martinez and Mejia to determine if there was

manifest need for the belts. Pinchak noted that he had objected “to protect the record to also show my client that I’m working for him so I would have a better client control.”

At the court’s invitation, the prosecutor laid out several rules violations Mejia committed while in prison. The court itself then read into the record a number of rules violations Martinez committed.

Haberer then shared his concerns with the court. He noted that the belts did not prejudice the defendants because the jury could not see them. Haberer expressed his concern for his safety, noting both defendants already were serving life sentences and had a “nothing to lose” attitude: “that’s scary to me.” He was also concerned by the “unpredictability” of his client’s personality, who could appear “happy-go-lucky, charming” in contrast to the nature of the charges. Haberer objected to a suggestion that he sit between Martinez and Mejia, because his carotid artery “is exposed to everything,” and his client had a “history of being able to secrete weapons.” He noted that “[i]nstead of paying attention to the trial, my peripheral vision has to be on alert all the time. It reduces my ability to focus.”

Pinchak objected to his seat being moved because “[i]f something happens, I have plenty of space to move away.”

The court ultimately found there was manifest need for both Martinez and Mejia to wear stealth belts. The court also ordered extra bailiffs in the courtroom.

During the trial, the jury saw surveillance video of the attack. Ten correctional officers testified.

The jury convicted Martinez and Mejia each of attempted premeditated murder and assault with a deadly weapon by a state prisoner (§ 4501, subd. (a) (§ 4501(a)).

The jury also convicted Mejia of assault with malice aforethought (§ 4500).

Whether § 4501(a) and section 4500 are different crimes or are essentially the same crime on the facts here is an issue in this appeal. Prosecutors had charged Mejia but not Martinez with two different assault crimes, apparently because the prosecution was uncertain exactly which of these theories jurors might accept, given that Mejia was not the one who plunged the weapon into the victim. Jurors, however, accepted all of the prosecution’s theories, thus raising the issue of possible duplication, which as we shall see the prosecution now concedes.

II

Martinez and Mejia appeal their convictions on three bases.

First, Martinez and Mejia claim a violation of their constitutional rights to be present at all critical proceedings and to conflict-free counsel. Because they do not show prejudice, these claims fail. Second, they argue section 954 prohibits multiple convictions based on the single act of stabbing. As the prosecution agrees, we must reverse Mejia’s conviction for § 4501(a), for it essentially duplicates his conviction for section 4500. We affirm all other convictions. We reject an argument about prosecutorial misconduct because there is no showing of prejudice.

A

Martinez and Mejia argue the court violated their constitutional rights in two interrelated ways. First, they argue the court violated their constitutional right to be present at a critical proceeding when they were absent from the hearing discussing security measures. Second, they argue this exclusion prevented them from realizing their counsel had conflicts of

interest: the lawyers were worried about the lawyers’ own safety as well as the clients’ best interests. Their claims fail. Prejudice is required, but Martinez and Mejia do not show it.
