SAN ANTONIO – Police have arrested two more men on federal charges who may be connected to the investigation of a deadly drive-by shooting.
De-Earlvion Whitley, 4, was killed last month in that shooting.
Tramone Anderson and John Chatman have both been arrested for felony possession of a firearm -- though neither man was arrested specifically for the shooting.

A federal grand jury indicted Chatman on Wednesday.
San Antonio police are still investigating the deadly shooting and have not arrested nor charged anyone with the crime.
Court documents, however, show federal agents detailing what happened before and after the shooting.
Two days after the shooting, the FBI raided a stash house it says belongs to Charles Bethany.
Agents seized cocaine and a video-surveillance system -- and arrested Bethany on federal drug charges.

That video shows footage of Anderson the day of the shooting. Agents said they saw him leave the stash house right before the shooting and come back right after.
As the video continues, it then shows Bethany trading Anderson an AR-15 for a revolver.
Anderson has multiple felony convictions in Bexar County, including evading arrest, detention with a vehicle and an enhanced charge of assault causing bodily injury to a family member.

As for Chatman, it has not been made clear as to why and how federal agents are connecting him to the same investigation.
Both Chatman and Anderson face up to 10 years in prison and a $250,000 fine if convicted.
