James Thomas Grigsby, 25, of Thayer, allegedly assisted with disposing of the victim’s body.
James Thomas Grigsby, 25, of Thayer, is charged with abandonment of a corpse and tampering with evidence in the death of 17-year-old Joseph Steinfield. He is held without bond in the Texas County Jail.
Three others were charged last week with allegedly murdering Steinfield in a home northeast of Cabool. Steinfeld had been reported missing by his family in early September.
Steinfeld’s sister, Ashleigh Boswell, told the Springfield News-Leader that the victim –– who also went by “Ally” and used the pronouns ‘she’ and ‘her’ on social media –– had talked to the family about being transgender and possibly having gender-reassignment surgery one day. Boswell said she didn’t know if her sibling’s gender identity might have been a factor in the murder.
According to a probable cause statement from the Missouri State Highway Patrol, investigators interviewed Grigsby on Friday –– one day before his birthday –– after learning he had assisted sometime between Sept. 3 and 9 in the disposal of Steinfeld’s remains. Grigsby admitted to authorities he had assisted the three murder suspects –– Andrew Vrba, and his girlfriend, Isis Schauer, both 18, as well as Briana Calderas, 24, of Cabool.
The patrol said Grigsby stated Vrba told him he killed Steinfeld. He said Vrba and the women picked him up from his Thayer home and took him to Calderas’ home at 14551 Malbert Road near Cabool.
Vrba had previously confessed to stabbing Steinfield in the living room and with the help of the women, wrapped up his body, moved it outside and burned it.
Human bones were found at the scene. Apparent blood stains and a knife were discovered inside.
Vrba, Schauer and Calderas were charged with first-degree murder and abandonment of a corpse. Vrba and Schauer were also charged with armed criminal action. All three appeared in court for arraignment Monday afternoon.
