A man who fatally shot a 15-year-old boy who was looking for his lost phone in a Tampa apartment complex last month won’t face criminal charges, police announced Thursday evening.

Detectives presented the facts of the Sept. 20 shooting of Heitor Amaral to the Hillsborough State Attorney’s Office, which determined that no charges will be filed, the Tampa Police Department said in a news release. Prosecutors decided they would be unable to refute the shooter’s claim of shooting Heitor in self-defense during a struggle on the man’s back patio.

The release does not identify Heitor by name, but the Tampa Bay Times reported his name earlier Thursday after confirming his identity with his sister. The Times story also included an account shared by the mother of one of the two other teen boys who were with Heitor that afternoon when they went to look for Heitor’s lost phone in the The Club at Hidden River, a complex of apartments and townhomes off Fletcher Avenue near Interstate 75.

Police did not release the shooter’s name.

“We recognize the profound pain and concern this tragedy has caused for the family and friends of those involved, and for our entire community,” Tampa police said in Thursday’s news release. “To ensure full transparency, the Tampa Police Department is releasing the established sequence of events surrounding the incident.”

According to the department’s account, Heitor realized he had lost his cellphone after leaving a “local establishment,” the release says. The following day, he and two friends used tracking technology to pinpoint the general area of the device, which indicated a location near the 13000 block of River Willow Place.

Seeking to retrieve the phone, the teens entered the gated community through an open gate, leaving their truck in the middle of the roadway. After being asked by a community member to move their truck, they went door to door asking residents if anyone had the phone.

After receiving no answer at the front door of one home, the teens went to the backyard, entered an enclosed back patio and began banging on the sliding glass door, according to police. A man in his 20s who lives in the home told police he “put on a mask and armed himself to scare off the individuals he observed on his private back patio attempting to access his sliding glass door,” the release states.

“Evidence shows that as the other teens fled, a physical altercation ensued just outside the enclosed patio between the (Heitor) and the resident,“ the release states. ”During the struggle, the resident stated he was placed in a headlock and feared for his life, at which point a single round was discharged from the gun, striking (Heitor).”

Officers responded to a 911 call about a fight and found Heitor critically injured. He died at the scene.

The shooter cooperated with investigators and turned over his gun. Heitor’s phone was not inside the shooter’s home and has not yet been found.

The news release cited a Florida statute known as the stand your ground law. It says, in part, that a person is justified in using or threatening deadly force if they believe it is necessary to “prevent imminent death or great bodily harm to himself or herself or another,” or to prevent an imminent forcible felony.

The Times story published earlier Thursday included an account from Yessenia Gonzalez, whose 16-year-old son Julio was with Heitor and the other teen.

Gonzalez said Julio, Heitor and the other boy went out that Saturday night to a club for teens. At some point, Heitor lost his phone, Gonzalez said. The teens share their locations through their phones, so the next morning, Julio was able to see where Heitor’s was located.

Gonzalez was in Pinellas County and told her son to wait for her to get home so she could accompany them. Julio worried they would lose track of the phone if the person turned it off. Gonzalez told him to call the police before they knocked on the door where the phone appeared to be.

Julio drove the trio to the complex in Gonzalez’s pickup and found one of the entrance gates open. They began knocking on doors along River Willow Place, a circular street lined by two-story townhomes. Residents at the first two homes said they didn’t have the phone, Gonzalez said.

After they knocked on athird door, a man wearing a mask and armed with a gun emerged from the back of the home and started to chase and fire at the teensas they ran away, according to Julio and the other boy’s account.

According to Gonzalez, Julio and the other teen said they did not get into a fight with the shooter, but Heitor fell behind as the trio ran away. Julio and the other teen lost sight of Heitor and soon after heard gunshots, Gonzalez said.

Heitor’s sister Maysa Amaral, 24, previously told the Times that her brother was not the type to start a fight.

“So unless unless the other party instigated a fight, or unless the kids were trying to actually physically protect themselves, I don’t see them starting a fight,” Maysa Amaral said.

Gonzalez said her son and Heitor had been friends for about eight years. Heitor was a respectful teen and a good influence, she said, the type of kid parents feel comfortable letting their kids hangout with.

The youngest of three, Heitor was a caring and family-oriented boy, Maysa Amaral said. She said her brother loved playing video games and listening to hip-hop, hanging out with friends and zooming around on an electric bicycle his father had recently given him.

Reached Thursday evening after a police detective notified them about the decision, Maysa Amaral said her family did not want to comment.

Gonzalez said in a text message that Heitor must have been scared by the man coming at him with a mask and that she still has questions about what happened. But she said she’s glad the investigation is closed because Heitor’s family “needs to rest.”
