CHICAGO (AP) — A Chicago-area man suspected of taking part in the 2009 killing of a teenager who was beaten and shot before his body was set on fire was added Thursday to the FBI’s 10 Most Wanted Fugitives list.

Luis Macedo was charged with first-degree murder in the slaying of 15-year-old Alex Arellano. Four others were quickly arrested and in 2013, a 19-year-old Chicago man was sentenced to 60 years in prison, becoming the latest of four suspects who were convicted and sentenced to lengthy prison terms.

FBI Director James Comey said at a news conference Thursday that Macedo is the 507th person on the list and 475 have been caught.

“We are trying to shine a very bright, very hot light on Macedo,” Comey said.

He added that the reward for information leading to his capture could be up to $100,000.Though Macedo hasn’t been seen in years, authorities believe he is somewhere in the southeastern United States or Mexico.

Macedo, 28, of suburban Oak Lawn replaces Brenda Delgado on the list. Delgado was wanted for the killing of her ex-boyfriend’s new girlfriend in Texas and arrested in Mexico last month. Delgado faces charges of capital murder and unlawful flight to avoid prosecution in connection with the September death of Dr. Kendra Hatcher, a dentist.

In the Chicago case that Macedo is being sought in, Arellano was killed on July 1, 2009, after he had gone to a neighborhood miles from where he lived in the hopes of meeting girls he’d communicated with online, media accounts at the time said. As he walked down the street on his way to a friend’s house with three girls, he was confronted by members of the Latin Kings street gang. They demanded that he give the gang’s sign. But the teenager said he was not a member of the gang and even lifted up his shirt to show them that he had no gang tattoos, authorities said at the time.

His attackers beat him with baseball bats and then chased him into an unoccupied home after he ran away. There, they shot him in the head and set him on fire, prosecutors have said.

Just last month, the Chicago office of the FBI announced it was offering a $5,000 reward for information leading to the arrest of Macedo. At the time, the FBI said Macedo had ties to both the Chicago area and Florida.
