DALLAS WAYNE HEMMENWAY, Appellant V.

THE STATE OF TEXAS, Appellee

On Appeal from the 260th District Court Orange County, Texas

Trial Cause No. D210372-R

MEMORANDUM OPINION

A jury convicted Dallas Wayne Hemmenway of the second-degree felony offense of intoxication manslaughter, and pursuant to a post-conviction agreement, the trial court sentenced him to ten years, suspended, and placed him on community supervision. See Tex. Penal Code Ann. § 49.08. Hemmenway filed a Motion for New Trial based on alleged juror misconduct, among other things, which was denied

by operation of law. 1 In three issues, Hemmenway complains: 1) during the guilt or innocence phase, the jury entered into an improper agreement to find him guilty in exchange for probation as punishment, constituting jury misconduct that affected the outcome of the case and resulted in an improper guilty verdict; (2) the trial court committed reversible error in excluding evidence offered by appellant that would “indisputably” have established the jury only found him guilty because of an agreement regarding punishment, constituting reversible jury misconduct; and (3) Texas Rule of Evidence 606(b) is unconstitutional as applied to him in that it denied him due process of law to establish jury misconduct as contemplated by Texas Rule of Appellate Procedure 21.3(c) and (g). For the reasons discussed below, we affirm the trial court’s judgment.

BACKGROUND 2

The evidence at trial showed that after a night of drinking, Hemmenway and his brother, Tyra, were traveling home in Hemmenway’s truck. The evidence at trial showed the vehicle left the roadway and hit a tree. Trooper Michael Priest testified

1 At the outset of the appeal, we questioned our jurisdiction. The record establishes, however, that on November 2, 2023, the trial court sentenced Hemmenway and signed the original written judgment. On December 1, 2023, Hemmenway timely filed a Motion for New Trial.

2 Hemmenway does not attack the sufficiency of the evidence or any evidentiary rulings during the trial, so we limit our background discussion accordingly. See Tex. R. App. P. 47.1 (requiring appellate court to hand down an opinion “as brief as practicable” but addressing every issue raised and necessary to the appeal’s final disposition).

that the vehicle was “heavily-damaged[,]” and it appeared to be a “very high-speed impact.” Corporal William Cowart of the Orange County Sheriff’s Office also responded and testified that the vehicle was traveling at a high rate of speed. Tyra was ejected and died at the scene from multiple blunt force trauma injuries. Hemmenway suffered minor injuries, and an ambulance transported him to the hospital. Trooper Priest testified that Hemmenway could have been ejected, although he saw no serious injuries indicating Hemmenway was ejected from the vehicle at a high rate of speed.

There was conflicting evidence about who was driving. Bodycam video admitted at trial showed that after telling officers Tyra was driving, Hemmenway admitted to Priest that he was driving, and Cowart testified that Hemmenway indicated to him at the scene that he was in the driver’s seat. DNA evidence showed that Tyra was the sole contributor to blood found on the passenger side airbag, and Hemmenway was excluded as a contributor to the blood tested on the airbag. Testimony and toxicology results established that more than two hours after the accident, Hemmenway’s blood alcohol content was .241, which is about three times over the legal limit.

Dylan Mooney, a witness from the gathering where the brothers drank alcohol before the accident, testified that when they first drove off, Dallas was in the driver’s seat with Tyra in the passenger’s seat. Mooney said that once the brothers got down

the driveway and to the main road, they stopped and cussed at each other about switching seats. According to Mooney, at that point, Tyra got in the driver’s seat, and “they burned off.”

A jury found Hemmenway guilty of intoxication manslaughter as charged in the indictment, a second-degree felony. After the guilty verdict, the State and Hemmenway entered a post-conviction sentencing agreement wherein punishment was assessed at ten years of confinement, suspended, and Hemmenway was placed on community supervision for ten years. 3 Per the probation order, Hemmenway also had to serve 120 days in jail, which would be scheduled on weekends.

MOTION FOR NEW TRIAL AND HEARING Hemmenway filed a Motion for New Trial, and as relevant to this appeal, he complains of juror misconduct. In the Motion, he argues that a new trial must be granted in the “interests of justice” due to juror misconduct. Hemmenway asserts that jurors discussed punishment “frequently” during guilt/innocence, and it was “used as a way to sway jurors that had initial vote of ‘not guilty’ into a vote of ‘guilty’ because the guarantee that probation would be given in the punishment phase.” He notes that the court’s charge instructed the jurors that “your sole duty at this point is to determine whether the defendant has been proved guilty. You must restrict your

deliberations to this matter.” In support of these arguments, he cites to Buentello v. State, 826 S.W.2d 610, 614 (Tex. Crim. App. 1992). Hemmenway does not assert in his Motion for New Trial that Texas Rule of Evidence 606(b) is unconstitutional as applied to him.

In support of the Motion for New Trial, Hemmenway attached the affidavit of Brenna Hansen, the defense’s private investigator. In Hansen’s affidavit, she outlines conversations she had with four jurors. According to Hansen, one juror told her that four members of the jury “didn’t believe Hemmenway was guilty, but they decided they could move forward with a guilty verdict when the group agreed to not give any jail time to Dallas Hemmenway.” Another juror told her he “didn’t think there was enough evidence from either side” and that “the jury did discuss punishment, but not for long.” Two others reported to her the jurors wanted his punishment to be light and to “give him the full extent of parole.”

On January 11, 2024, the trial court held a hearing on the Motion for New Trial. At the hearing, Hemmenway noted that he subpoenaed four jurors who participated in the deliberations to testify. The State objected to the jurors testifying under rule 606(b), which it claimed overrides Buentello. The State argued that the law is clear the only things jurors could testify to in post-conviction matters was (1) outside influence or (2) their qualifications to serve as jurors. The State asserted that none of the jurors would testify about those two things. Hemmenway agreed that the

jurors would not testify about outside influence, rather they would testify they made an internal agreement relating to punishment in exchange for a guilty vote.
