June 22 (UPI) -- A judge in the Charlie Kirk murder case dismissed a motion Monday by attorneys to subpoena Tyler Robinson's former romantic partner to testify in person at a hearing in July.

Robinson, 23, is accused of killing right-wing activist Kirk as he spoke at a university in Orem, Utah, last year. At the time, Robinson lived with Lance Twiggs, whom the attorneys sought to subpoena.

Prosecutors moved to quash the subpoena and said they intend to use a recorded interview and messages between Twiggs and Robinson. Twiggs, who is considered a material witness, allegedly received several text messages from Robinson on the day Kirk was shot.

The defense said Twiggs should testify because the conversations between Twiggs and Robinson are being used as the basis for seeking the death penalty, KTVX-TV reported.
