BRUNSWICK, Ga. -- The father of Antonio Santiago is in jail on charges of aggravated stalking, according to a warrant obtained by Action News.
Action News first spoke with Louis Santiago and Sherry West after baby Antonio was shot and killed in March.

At the time, they were two grieving parents mourning the loss of a sweet little boy.
But an arrest warrant from June 6 says Louis Santiago was stalking West and is now in jail. Police say Louis Santiago was found standing on her porch, in violation of police orders.
Santiago is charged with Aggravated Stalking. He was convicted of the same charges in another case from 2009.
That 2009 conviction is also cited in a motion filed by lawyers for baby Antonio's accused killer, DeMarquis Elkins. The motion also asks a judge to put the full GBI report from the March shooting on the record.
Elkins is accused of shooting West and killing her baby during a robbery attempt. Another teen, Dominque Lang is also charged in the killing.
The GBI found gun shot residue on both Sherry West and Louis Santiago shortly after the killing.
The fact that West was shot during the robbery attempt could explain why investigators found residue on her.
As for Louis Santiago, the GBI lab report says finding gunshot residue on a person could indicate that they were holding the gun when it was fired, been near a gun that was fired, or came into contact with a surface that has gun shot residue on it.
Police have never named Sherry West or Louis Santiago as suspects in baby Antonio's murder.
