CHICAGO (ABC) — A convicted felon was arrested in connection with the “unspeakable” murder of 9-year-old Tyshawn Lee in Chicago, police announced Friday — one of “at least three” suspects allegedly involved in the case, Chicago Police Superintendent Garry McCarthy said Friday.

The suspect, Corey Morgan, 27, was charged with first-degree murder in the “execution” of Tyshawn, who police said was lured to an alley and shot several times in the upper body, including the head and the chest, on Nov. 2.

This is not Morgan’s first encounter with police — he is a convicted felon and registered gang member, McCarthy said. Just a few weeks ago, police said they picked him with a firearm.

The status of the case was not clear.

McCarthy described Morgan as an individual with “extensive violent criminal history who likely shouldn’t have been on the streets.”

Of the other two suspects, one — whom police did not name — is in custody on a gun charge unrelated to Tyshawn’s killing and is expected to be charged with first-degree murder. The suspect has not yet been formally charged.

An arrest warrant on first-degree murder charges will be issued for the third suspect, who police Friday identified as Kevin Edwards.

One of the suspects was a driver, another was the triggerman, but it was not clear which of the suspects was allegedly responsible for which role.

Police said identifying the suspects was possible because of community intelligence and detective work.

“There was a lot of fear,” he said, praising the community for coming forward with information.
