Prosecutors ask judge to revoke pretrial release for Vinton woman accused of involvement in accidental shooting

Prosecutors are again asking a federal judge to revoke a Vinton woman's pretrial release for alleged violations.

Robyn Merchant, 53, is charged with giving her 16-year-old son a rifle that was unintentionally fired by another teen, killing 14-year-old Emma Redlinger on Feb. 24, 2015 in Merchant's home.

Prosecutors asked the court last month to revoke Merchant's pretrial release because she lied about her drug usage to probation officers and she missed urine screenings, but U.S. Chief Magistrate Jon Scoles said they were not sufficient violations to revoke. He did however, give her a stern warning, saying if she tested positive again, he would send her to jail.

A motion to revoke was filed Tuesday but it didn't state the alleged violations. A hearing is set April 19 on the possible revocation.

Merchant was charged last month with one count of providing a firearm to a prohibited person. She is accused of purchasing a Walther HK MPS 22LR semi-automatic rifle for her son Dillon Winterroth, 16 at the time, the day before Emma Redlinger was fatally shot last year.

Merchant, also known as Robyn Winterroth, admitted to investigators that she knew her son was using marijuana.

An investigator testified last month that teens told a grand jury that Dillon Winterroth was dealing drugs out of the home and they also purchased drugs from Merchant when he was gone.

William Hines Jr., Winterroth and another teen were passing around the gun that day in Winterroth's bedroom when it discharged, juvenile petitions show. She died four days later.

The teens initially lied to police about what had happened, but Hines eventually admitted to holding the gun when it discharged, according to the petitions.

Merchant's son, Dillon Winterroth, now 17, pleaded guilty last month in juvenile court to misdemeanor drug charges.

Hines is charged with involuntary manslaughter, interference with official acts and harassment of public officers and employees, and will be tried as an adult.
