PHILADELPHIA -- Three men were facing murder charges Saturday in connection with the fatal beating of a Philadelphia man last weekend, police said.

Felix Carrillo, 23, Stephen Ferguson, 20, and Kenneth Santiago, 19, were arrested Friday and charged with the murder of Kevin Kless, WTXF-TV reported.

Kless, 23, was trying to hail a cab for himself and two friends when the attack occurred in Philadelphia's Old City after bars let out in the area in the early hours of last Saturday.

Kless' companions said an available taxi did not stop to pick them up and Kless gestured at the car.

Police surmise that his attackers thought he was making gestures at them when they jumped out of a car and began to beat him. He was pronounced dead at a local hospital a short time later.

One of the suspects confessed to the crime, a police source told the Philadelphia Inquirer.

A $20,000 reward had been offered for information leading to the assailants, WTXF-TV reported.

Kless, a 2010 graduate of Temple University, was a Warwick, N.Y., native and had just returned to Philadelphia to start a new job, according to the Times Herald-Record. A memorial service was held Friday in Warwick.
