Two of four people suspected of participating in the beating death of a 28-year-old man outside Pat’s King of Steaks in South Philadelphia last week have turned themselves in to police and were expected to be charged with murder, authorities said Monday.

Police identified the men as Omar Acre, 32, and Jose Alberto Flores-Huerta, 33, both of South Philadelphia. Police said the men would also face counts of attempted murder and other charges for the killing of Isidro Cortes and the assault of Cortes’ father and another man during a brawl outside the landmark cheesesteak shop after a soccer game in Chester.

Neither man had been arraigned as of Monday evening. It was not clear if either had a lawyer in the case.

Even as authorities announced their surrender, they said two other suspects remained at large.

Police issued arrest warrants Sunday

for Osvaldo “Willie” Pedraza, 34, of the 2600 block of East Norris Street in Kensington, and Victor Pedraza, 32, of the 1400 block of South Percy Street in South Philadelphia. They had not been apprehended as of Monday evening, said Homicide Capt. Jason Smith. Both are wanted on charges of murder, attempted murder, and conspiracy.

The melee they are accused of escalating erupted around 2 a.m. Thursday, police said, several hours after Cortes, of Queens, N.Y., had attended a Concacaf Champions League semifinal in Chester between the Philadelphia Union and Club América, a team from Mexico City.

Cortes, his father, and another man, whom police have not identified, were all wearing Club América gear and eating cheesesteaks when they began talking to a group of people at the restaurant who were also wearing Club América jerseys. An argument broke out, police said, and the other men began assaulting Cortes and his group, according to video police released Friday — knocking them to the ground, punching them and kicking them as they lay bloodied, and using part of a trash can to continue the attack.

It is not yet clear what may have prompted the brawl. Smith said last week that video appeared to show the groups interacting without hostility before the situation suddenly turned violent.

Friends of Cortes organized a GoFundMe campaign to help pay for funeral costs, describing him as “full of life, happiness, and laughter” and saying he was a passionate fan of Club América.

Chesley Lightsey, homicide chief of the District Attorney’s Office, said there have been “a lot of tips called in” about the case, which remains under investigation.

“We are happy with how this investigation is coming together,” she said.
