S26A0053. HERNANDEZ v. THE STATE.

PINSON, Justice.

Gustavo Hernandez was convicted of malice murder and other crimes related to the shooting of Daniel Perez.1 On appeal, Hernan-

1 Perez was shot on March 23, 2018, and died a few days later. A Cobb

County grand jury returned a joint indictment charging Hernandez and four others with several crimes related to the shooting. As relevant here, Hernandez was charged with malice murder, three counts of felony murder, aggravated assault, criminal attempt to commit a felony (armed robbery), conspiracy to commit armed robbery, and possession of a firearm during the commission of a felony. He was tried alone by a jury on August 23 to 27, 2021. The jury found him guilty of all counts. On September 1, 2021, the trial court sentenced him to life in prison for malice murder, a consecutive sentence of 10 years in prison for conspiracy to commit armed robbery, and a consecutive five years in prison for possession of a firearm during the commission of a felony; the felony murder charges were vacated by operation of law, the aggravated assault charge merged with the charge of malice murder, and the charge of criminal attempt to commit a felony merged with the charge of conspiracy to commit armed robbery. Hernandez timely filed a motion for new trial through his trial counsel on the same day he was sentenced. Hernandez later changed counsel, and on February 7, 2025, he filed an amended motion for new trial, which raised claims that trial counsel was ineffective. After a hearing on March 26, 2025, the trial court denied the motion for new trial on April 10, 2025, and

dez contends that his trial counsel rendered constitutionally ineffec- tive assistance by failing to object to several arguments made by the State in closing. For the reasons that follow, Hernandez has not es- tablished that counsel’s performance was deficient, so his claims fail and his convictions and sentences are therefore affirmed.

1. The evidence at trial showed the following. On March 23, 2018, Hernandez, Charlton Kariuki, and Devin Thomas discussed robbing someone. Thomas then sent a message to Perez on social media about an opportunity to sell a “good amount” of marijuana. Perez showed the message to his girlfriend, who thought this pro- posal was “fishy” because Thomas had once set up Perez with a pur- ported buyer who stole five- or six-hundred-dollars’ worth of mariju- ana from Perez.

Dismissing his girlfriend’s concerns, Perez asked his brother, Ricky Perez, to give him a ride and put a location into his GPS. Ricky drove, following the GPS directions until Perez told him to take a

right into a parking lot across from North Cobb High School instead. Ricky turned into the lot and parked. Someone approached their truck and spoke to Perez through the open passenger-side window. Someone else then came toward the truck and shot Perez through the open window. Ricky had been looking at his phone and “barely” saw the shooter, but he testified that it looked like the shooter was trying to take something from Perez and then ran away.

Ricky called 911, and Perez was taken to the hospital. He died three days later from complications related to a gunshot wound to his head.

After the shooting, Perez’s girlfriend told the police about the social media messages Perez had exchanged with Thomas that day and identified Thomas in a photo. Someone else also contacted the police and told them that Thomas may have been involved in the shooting.

Thomas was taken into custody, and Maria Mungai, who lived with Thomas and was with him at the time of his arrest, was

brought in for questioning. Investigators read Mungai her Miranda2 rights, and she agreed to speak with them. At first Mungai said the incident with Perez was a “drug transaction,” but then “she changed her story and said that it was basically a robbery that had gone wrong.” She identified Hernandez, Brittani Driver (Hernandez’s sis- ter), Thomas, and Kariuki as the people involved.

Thomas, Kariuki, Driver, and Mungai were all jointly indicted with Hernandez. Driver, Kariuki, and Mungai testified at Hernan- dez’s trial pursuant to plea agreements with the State.

Kariuki testified that Thomas told him that he wanted to rob three people in different places, and that “it should be quick ... get it and go.” Kariuki then drove Hernandez, Thomas, Driver, and Mungai to a spot near North Cobb High School. According to Kari- uki, Thomas got out of the car, and Driver, Hernandez, and Mungai remained with Kariuki, who drove around the area until he found a parking spot and parked. Kariuki testified that “a couple seconds, minutes [went] by” and then Hernandez said he wanted to get out of

the car to urinate. Hernandez then got out of the car and said he would “be right back.” But according to Driver, Thomas and Hernan- dez got out of the car together and walked away. And according to Mungai, Driver told Kariuki where to park and told Thomas to go in one direction and Hernandez to go in another direction when they got out of the car together.

Kariuki testified that, soon after Hernandez got out of the car, he heard a “loud boom” that sounded like a gunshot and everyone in the car started “panicking.” Kariuki said that Driver wanted to get out of the car and see what had happened, but he stopped her. They waited “a couple minutes,” and then Kariuki saw Thomas and Her- nandez “running down the street,” “put the car in gear,” and drove to them. Driver testified that Thomas and Hernandez had been “gone for a couple minutes” when she heard what sounded like a gunshot, and then Thomas and Hernandez “came running back to the car.” Mungai testified that she heard a gunshot less than a mi- nute after Hernandez and Thomas got out of the car. Soon after that, she saw Thomas and Hernandez “running back towards the car.”

Kariuki testified that, after Hernandez and Thomas got back inside the car, Hernandez said, “I shot him, I shot him. Bro, I shot him in the head. I shot him. I didn’t mean to. I shot him.” And Thomas said, “He shot him, he shot him. I didn’t even get the weed yet.” Driver testified that Hernandez said, “I think I just shot him in the head.” She also said that Hernandez was “panicking” and “couldn’t believe what he had done.” Mungai testified that Hernan- dez said, “I just shot that ‘N word’ in the head.”

After the shooting, Kariuki drove Hernandez and Driver to their home. Kariuki and Driver both testified that Hernandez had a gun with him on the day of the shooting. Kariuki testified that he had recently bought a gun for himself, and then he sold it to Her- nandez. The day after the shooting, Kariuki drove Hernandez, Thomas, and Mungai to a park near the Chattahoochee River, and Hernandez threw the gun he had bought from Kariuki into the river.

When the police arrested Hernandez, they also executed a search warrant at his home. During the search, investigators found a store receipt for ammunition that matched the caliber of the bullet

collected at the crime scene. Surveillance footage from that store showed Kariuki, Thomas, Mungai, and Hernandez shopping. Kari- uki testified that he bought ammunition that day (because he was the only one old enough to do so) and gave it to Hernandez.
