Just after 1 p.m. Friday afternoon, jurors in the 15th State District Court convicted Tyrone Sommers in the Oct. 31, 2017 shooting of Robert Allen in Denison. He was convicted of conspiracy to commit murder, criminal in possession of a firearm, and tampering with evidence for throwing the gun used in the Lake Texoma shooting.

They were expected as a penalty on Friday afternoon.

Jurors of the 15th State District Court heard closing arguments Friday morning in the state’s case against Tyrone Sommers during the Oct. 31, 2017 shooting of Robert Allen in Denison.

At 10:45 the jury started deliberating

Sommers is the second person to be tried in the murder and charged with conspiracy to commit murder, criminal in possession of a firearm and tampering with evidence.

Tyrone Somers

In April, Timothy Barnum was convicted of murder in the case and was sentenced to life in prison. This week, Grayson County First Assistant District Attorney Kerye Ashmore and Assistant DA Nathan Young presented witnesses proving that Sommers colluded with Barnum in Allen’s death.

The state claims Barnum wanted Allen dead, but because of their history of family disagreements over the treatment of Allen’s daughter and the child she shared with Barnum, he knew he would be a suspect if Allen was killed. Prosecutors said Barnum had asked his father to kill Allen, and when that failed, he asked his second cousin Sommers.

In his closing statement Friday, Ashmore reminded jurors that after Allen’s death, Sommers ended up with a car and house that once belonged to Barnum. Ashmore reminded them of phone records and testimony that he said showed Sommer was near Allen Plumbing in Denison the night Allen was murdered. Ashmore said that while Sommers initially denied knowing anything about the murder, he eventually admitted that he was with Barnum the night of the murder and that he had lost the weapon that police believe was used in the shooting.
