Things have taken another turn in the case of a teen shot and killed in a Cape Coral street on St. Patrick's Day.
The Lee County Sheriff's Office says they've arrested one of the suspects' mother.
Thomas Stein and Christopher Horne are accused of killing Kayla Rincon-Miller during a bizarre robbery attempt.
Both are 16 and both are charged as adults.
Horne's mother is now facing allegations - charged with obstruction of justice.
The Lee County Sheriff's Office says they're investigating witness tampering where Stein and his family were threatened at gunpoint by Horne's family.
Deputies say Thomas Stein's mother was ordered not to speak to police, or another one of her children would be harmed.
In court on Thursday, the prosecutor asks, "Who are the people that were identified with tampering her and her son?".
The deputy responds, "Ultimately identified in the case were Shanice Stewart Christopher Horne's mother, Faraka Stewart his aunt, and Christopher Horne senior - his father."
We also learned that following the March 17th murder, the Horne family moved their belongings out and left their home.

That's according to the Lee County Sheriff's Office.
Investigators say that is why it took officers nearly a month to find Horne and arrest him.
The judge denied bail for Horne Thursday, as prosecutors reminded the court Horne posed a risk to public safety.
The Cape Coral Police Department says more arrests are possible.
