LYNN — Aliakbar Zangiband stood before a utility pole Wednesday afternoon bearing photographs of his slain son — a delivery driver who was killed in what police believe may have been a case of road rage.

At the same spot where 24-year-old Mohammadreza Sina Zangiband died two days earlier, his father wrapped his arms around the pole and kissed a portrait of the murdered man.

“Everybody’s crying for him,’’ said the elder Zangiband, an Iranian immigrant who came to the United States as a refugee. “My son is no more.’’

Hours earlier, prosecutors announced Brian G. Brito, 21, had been charged with killing Zangiband, who was shot Monday at about 5:50 p.m. as he took a shortcut in Lynn while making food deliveries for Atha’s Famous Roast Beef.

The aspiring commercial pilot who went by Sina was to turn 25 years old next week. He moved to Massachusetts from Iran when he was 13, and was a US citizen.

Brito, who lists addresses in North Andover and Manchester, N.H., is to be arraigned Thursday in Lynn District Court on a charge of first-degree murder, the Essex district attorney’s office said. His defense attorney didn’t respond Wednesday to requests for comment.

Zangiband’s sister, Soma, said nothing will bring him back.

“It was good to know that [Brito] finally got charged with what he did to my brother, but my family will never be the same,’’ she said.

The killing occurred outside St. Pius V School on Bowler Street after a gray Audi overtook Zangiband’s 2012 Hyundai Sonata and forced it to pull over, according to a police affidavit filed in court.

The affidavit included the accounts of three witnesses and summarized evidence taken from neighborhood surveillance cameras. The videos led investigators to believe that the confrontation “may have been the result of a road rage incident,’’ wrote State Police Trooper Thomas J. Sullivan IV.

One of the witnesses, an off-duty firefighter, said a man exited the Audi, walked around the car, and pointed a black semiautomatic handgun at Zangiband, shooting him four to five times.

“The man then returned to the Audi, looked directly at [the witness], got back into his car, and left the scene,’’ Sullivan wrote. The witness provided police with information about the New Hampshire license plate on the Audi.

Officers found Zangiband inside the Sonata suffering from at least one gunshot wound to the head and his foot depressed on the brake pedal, the affidavit said. The vehicle was shifted in reverse.

Video surveillance “tends to corroborate’’ the off-duty firefighter’s account, Sullivan wrote. One video showed the Audi with its passenger-side window open or missing as it attempted to overtake the Hyundai. A second video showed the Audi following the Hyundai, the affidavit said.

In interviews with investigators, another witness said he heard gunshots from behind his car and saw a man dressed in black fire into a stopped vehicle before fleeing, Sullivan wrote.

A woman who lives nearby said she heard four gunshots from inside her home, the affidavit said. When she looked outside, she said she saw a dark-colored Audi drive slowly toward her house before accelerating toward Lake Street.

Essex District Attorney Jonathan Blodgett said many officers gathered the evidence to charge Brito with murder.

“This was a brazen, senseless act that not only took the life of a hard-working young man, but also frightened community members,’’ he said in a statement.

Troopers arrested Brito Monday night after they spotted the Audi, which was sought in connection with the Lynn homicide, on Route 1 South in Peabody.

While searching him, police recovered a loaded, 9mm semiautomatic firearm with one round in the chamber, a loaded magazine, and a box of 9mm ammunition, a police report said.

After troopers took Brito into custody, they learned he might also be wanted in North Andover for a rape and armed robbery that happened after the fatal shooting in Lynn, authorities said.

In that case, a Richdale convenience store clerk said she was attacked by a man armed with a black gun and dressed in a black ski mask and gloves, another police report said.

The attacker thanked the clerk for “making this easy,’’ the report said.

“I had to kill someone today that made it hard,’’ the assailant allegedly said. “I’m going to leave you some money.’’

Investigators linked Brito to the North Andover assault after matching his clothing, backpack, and weapon to the suspect seen on store surveillance video, the report said.

Brito was arraigned Tuesday on illegal firearm and ammunition charges filed by troopers who pulled him over in Peabody.

He pleaded not guilty and was ordered held without bail pending a dangerousness hearing next month.

Brito is to be arraigned Monday in Lawrence District Court on charges linked to the North Andover attack, prosecutors said.

Back on Bowler Street, mourners left flowers and lit candles in honor of Zangiband.

“I miss him. I just want him back,’’ said Zangiband’s girlfriend, Luxana Perez, 20. “He was the sweetest guy.’’

Earlier Wednesday, Zangiband’s mother, Shahin, sat barefoot on her couch in Salem and cried out for her son while a friend comforted her in their native Farsi.

“Sina! Sina! Sina!,’’ she said, over and over.
