Four people are now under arrest in connection with the shooting death of a Carrollton teenager.

Police say 13-year old Nizzear Rodriguez was shot to death in his grandmother's townhome while he was sleeping in his bed.

Investigators arrested 17-year old Malik Davis just hours after the murder.  He made his first appearance in Magistrate Court Tuesday afternoon on murder, burglary, home invasion and weapons charges.

Police arrested three more people Tuesday afternoon.  Kenneth Wheat, 21, is charged with murder and burglary.  Jackquline Leann Freeman, 24, is charged with murder as well.  Police think she was the getaway car driver.  They charged a fourth person, Oleida Ward, 34, with making false statements during the investigation.

Police would not comment on a possible motive, but Rodriguez's family believes Davis and Wheat broke into the home to rob it.

In court, a magistrate judge stated police believe Davis stole a PlayStation out of the home.

Rodriguez's aunt, Kanisha Osorio, said Wheat was a frequent guest at their home.

"It was shocking that someone that's in your house, my mom is feeding him," said Osorio.  "For someone to do something like that to my nephew, it was shocking."

Osorio believes the suspects were trying to rob her grandmother's home.

"We have PlayStation 4, nice TVs, nice shoes and all kinds of stuff, so you know, they could've wanted that,” she said.

Rodriguez celebrated his 13th birthday hours earlier, and Osorio said his grandmother was planning to take him to buy new shoes the day they discovered his body lying in bed.

Wheat's family spoke to Channel 2 Action News minutes after the arrest.  They said if Wheat really committed the crime, it would be inexcusable.

"If he did it, if he was there, there's no right in this," said Denise Wheat, the suspect's aunt.  "He's a 13-year-old kid, innocent kid, in his bed asleep.  If he did it, but I guess that's going to be a matter for the courts right now."

Carrollton Police Chief Joel Richards credits his investigators and the use of social media for the quick arrests in this case.

He also said he had a personal interest in catching the suspect because his daughter knew the victim.

"I can tell you, this kid was a jam-up kid," said Richards.  "What you hear from the community is true.  My daughter is a student at the same school he goes to."

Richards confirmed Wheat was recently released from prison where he served time for aggravated assault.
