BRUNSWICK, Ga. -- The search for justice for baby Antonio continues. The 13-month-old boy was shot and killed back in March.
Police say two teenagers tried to rob the baby's mother.
Those teen suspects are DeMarquise Elkins, 17, and Dominque Lang, 15.
Three more people were arrested on charges they tried to cover up the crime, all members of the Elkins family.
Mom, Karimah Elkins, and sister, Sabrina Elkins, are accused of hiding the suspected murder weapon. And aunt, Katrina Elkins, is accused of lying to police by providing DeMarquise with an alibi.

In just three weeks, DeMarquise, Karimah, and Sabrina will go on trial. And with the clock ticking, attorneys on both sides have spent the last two days combing over evidence, getting their cases ready for a jury.
Louis Santiago isn't on trial, but the father of the murdered baby found himself on the witness stand Friday. Still jailed on charged he had been stalking the baby's mother, Sherry West, Santiago relived that day when his baby was killed, and when he comforted West.
"I just held her and she was just crying," said Santiago.
He said he was at Walmart at the time of the shooting. But the defense isn't convinced. It recently released a GBI report showing Santiago had gunshot residue on his hands after the murder. Evidence, the defense said, that Santiago had been around a weapon.
Santiago said the gunshot residue could have gotten on his hands when he touched West after the shooting.
He said, "I saw a bullet hole for the first time. And I was just curious. I had to look. Like a kid."
As the defense worked to divert attention away from the Elkins family, the family sat quietly at the same table, never exchanging a look.
DeMarquise, 17, faces the most serious charges. Police say he was the one who fired the fatal shot at the baby's face. His mother and sister are accused of helping hide the murder weapon.
They are set to go on trial Aug. 19 in Cobb County, Georgia. The trial was moved to a different city because of all the pretrial publicity.
Sherry West, the baby's mother, was also subpoenaed to testify Friday. The defense has questioned her competency, saying she has mental health and drug abuse issues. She's one of two witnesses to the shooting.
The other witness is the other teenager charged with the murder, Dominique Lang, 15. He will have a trial of his own. As will Katrina Elkins.
Their trial dates have not yet been set.
