Ingham County Medical Examiner Dean Sienko said the most significant drug was Hawaiian Baby Woodrose seeds, which contains a compound — lysergic acid amide, or LSA — that can cause psychosis, including hallucinations.

Ausman’s blood and urine also contained THC-COOH, the chemical compound found in marijuana.

Ausman’s stepfather Jim Wauldron issued a statement on behalf of the family stating Ausman had taken the seeds with his roommate to ease pain from a recent boxing class. The seeds, which are legal in the U.S. according to the statement, were purchased on eBay.

“Don was told that this seed would relax him, give him a buzz, not cause potentially hazardous hallucinations,” Wauldron said in the statement.

LSA is characterized by federal regulations as a Schedule III substance, meaning a prescription is required to use it, but regulation of distribution is less stringent than other more common drugs, such as LSD.

MSU police Sgt. Florene McGlothian-Taylor said police determined through their investigation that Ausman had inflicted the knife wound on himself. She said police do not know why Ausman stabbed himself.

Ausman’s body was discovered the morning of Jan. 28 in his Spartan Village apartment by his roommate, who made the initial call to police. McGlothian-Taylor said Ausman’s roommate was questioned but was not a suspect.

In the immediate announcement over MSU’s text message crime alert system on the day Ausman’s body was found, police characterized the death as “suspicious,” but said the community was not in danger.

McGlothian-Taylor said the department did not release news of the stab wound earlier because investigators wanted to compile a full report.

“We needed to wait until we received autopsy and toxicology reports,” McGlothian-Taylor said.

The department received the reports late Monday afternoon but waited to release the information until after family had been notified, McGlothian-Taylor said. Ausman’s father’s family knew of the stab wound when investigators determined it as the cause of death, but his mother’s family had asked not to know until two weeks ago, McGlothian-Taylor said.

McGlothian-Taylor declined comment on the roommate’s involvement in the incident.

In the statement, Wauldron called Ausman a “happy, kind, thoughtful, popular, upbeat, great young man.”

The family declined further comment.

“He made a sad mistake,” the statement said. “He ate a legal, organic flower seed and he paid the price with his life.”
