Expert Witnesses & Meth

In State v. Richmond, the WA Court of Appeals held that a defense expert witness’s proposed testimony regarding the effects of methamphetamine was properly barred at trial because the expert never met or examined the victim and increased aggression is only one possible effect of methamphetamine ingestion.

BACKGROUND FACTS

Dennis Higginbotham went to Joseph Richmond’s property with two other individuals, Veronica Dresp and Lonnie Zackuse. Ms. Dresp was Mr. Richmond’s estranged girlfriend. Ms. Dresp had asked Mr. Higginbotham and Ms. Zackuse to accompany her to Mr. Richmond’s property so that she could remove some of her belongings.

A verbal argument ensued between Mr. Richmond and Mr. Higginbotham. After the verbal argument, Mr. Richmond went into his house. His return to the house was a relief. It appeared the hostility had come to an end.

Unfortunately, this turned out not to be true. Instead, Mr. Richmond ran out of his house, armed with a two-by-four piece of lumber that was nearly four feet in length. Mr. Richmond and Mr. Higginbotham then started exchanging more words. Mr. Richmond warned Mr. Higginbotham not to come any closer to him. When Mr. Higginbotham took a step forward, Mr. Richmond struck Mr. Higginbotham with the two-by-four. According to Ms. Dresp and Ms. Zackuse, Mr. Richmond held the two-by-four like a baseball bat and swung it at Mr. Higginbotham’s head. After he was hit, Mr. Higginbotham spun around and fell face first on the ground.

When emergency personnel arrived at the scene, it was determined Mr. Higginbotham had suffered severe head trauma. He was unconscious and eventually transported to
Harborview Medical Center in Seattle. He died shortly thereafter.

Mr. Richmond was charged with second degree murder.

Mr. Richmond lodged a self-defense theory against the State’s murder charges. In support of this theory, Mr. Richmond sought to introduce testimony from several experts. One of the experts was David Predmore. Mr. Predmore was offered to testify about the general effects of methamphetamine consumption on human behavior. According to the defense, this testimony was relevant because high levels of methamphetamine had been found in Mr. Higginbotham’s system at the time of his death.

Although Mr. Richmond was not aware of Mr. Higginbotham’s methamphetamine consumption at the time of the assault, the defense theorized that Mr. Predmore’s testimony was relevant to corroborate Mr. Richmond’s claim that Mr. Higginbotham was behaving aggressively the night of the attack. However, the trial court excluded Mr. Predmore’s testimony as speculative and irrelevant. The jury convicted Mr. Richmond of second degree murder. He appealed.

ISSUE

On appeal, the issue was whether the trial court violated Mr. Richmond’s constitutional right to present a defense by excluding his expert’s testimony.

COURT’S ANALYSIS & CONCLUSIONS

“Mr. Richmond argues the trial court violated his constitutional right to present a
defense by excluding expert testimony,” said the Court of Appeals. “We disagree.”

The Court of Appeals reasoned that Evidence Rule 702 governs the admissibility of expert testimony. “Under this rule, a witness may provide expert opinion testimony to the jury if (1) the witness is qualified as an expert, and (2) the witness’s testimony would help the trier of fact,” said the Court of Appeals.

“Expert testimony is helpful if it concerns matters beyond the common knowledge of the average layperson and does not mislead the jury. A proposed expert’s testimony is not helpful or relevant if it is based on speculation.”

Furthermore, the Court of Appeals reasoned that the trial court properly excluded Mr. Predmore’s proposed testimony regarding the effects of methamphetamine because it was not shown to be potentially helpful to the jury. “Mr. Predmore had never met or examined Mr. Higginbotham. He had no basis to assess how Mr. Higginbotham’s body may have processed methamphetamine,” said the Court of Appeals. It further reasoned that according to Mr. Predmore’s proposed testimony, methamphetamine can have a wide range of effects. Increased aggression is only one possibility. “It is therefore nothing but speculation to connect Mr. Higginbotham’s methamphetamine use with Mr. Richmond’s claim of victim aggression,” said the Court of Appeals. “The evidence was properly excluded, consistent with long standing case law.”

With that, the Court of Appeals upheld the conviction.
