The Faulkner County Sheriff's Office has subpoenaed a 17-year-old Mayflower suspect's phone records.

Nathan Casey, who is charged as an adult in a Jan. 12 incident, is currently being held in the county jail in lieu of a $500,000 bond and faces three counts of aggravated robbery. After listening to a jail conversation between Casey and his mother, authorities are asking to review the 17 year old's phone records to determine if he is involved in more than one robbery.

According to a search warrant affidavit filed in Faulkner County Circuit Court on Tuesday, the sheriff's office requested a circuit judge's permission to obtain the juvenile's phone records from AT&T following a conversation Casey had with his mother via a jail phone on Jan. 24.

"In the phone call he tells his mother to get the phone out of the house because 'they can't have it,'" the affidavit reads. "He tells his mother 'apparently I tried to hit a lick on somebody else that night, or something like that.' He then says 'you know, try to rob somebody else that night.'"

Court records indicate electronic data has been retrieved from the juvenile's phone via a "secure email" following Circuit Judge Troy B. Braswell Jr.'s approval to move forward with the search warrant.

Court records also show the teen's father, David Casey, faces a felony charge for allegedly threatening one of the victims in his son's case.

According to a probable cause affidavit, David messaged the victim over Facebook and told her she would "have to move out of town and move out of [the] state because I'll [explicit] kill you."

David, 41, of Mayflower was charged with intimidating a witness, a Class C felony, which carries a three to 10-year sentence range along with a fine of up to $10,000.

The victim told police David first offered to have his son and the other suspects involved in the Jan. 12 aggravated robbery incident clean for her in exchange for her to drop the charges. After she explained to David that the decision was out of her hands but that she did intend to pursue a civil case for personal damages, he allegedly began threatening her.

"I am Nathan's dad will you please take these charges off of him I will make him clean your house clean your car he ... [and] the other two will be your slave for the next six months please please please and thank you," David wrote in a Facebook message to the victim on Jan. 19.

David met with his son during visitation hours Jan. 20. The conversation was recorded, upon a circuit judge's approval.

During the conversation, Nathan tells his dad not to worry because the investigators "really don't have anything on him," according to an affidavit.

In the recorded conversation, investigators also heard David tell his son that he "tried begging [the victim] to drop the charges against his son and in exchange, the three suspects will come do yard work and house work for her." David said she turned down the offer, noting he then "talked to her all kinda crazy and I'm probably gonna end up in jail."

Nathan along with the other two teen suspects — Wayne Schutz III and Wayland Schutz — in the aggravated robbery case are set to appear next at 9 a.m. April 24 for a pretrial hearing. David is scheduled to appear at 9 a.m. Monday in Faulkner County Circuit Court for a plea and arraignment hearing.
