A Dallas woman charged with killing a Southern Methodist University student in a crash on a Central Expressway feeder road had nearly four times the legal limit of alcohol in her blood after the crash, according to a toxicology expert.

Testing on Lynlee Pollis hours after the crash showed she had a blood alcohol concentration of 0.294%, toxicology chemist Brittany Welch testified Thursday at Pollis’ trial in Dallas County state district court. The legal limit for driving in Texas is 0.08%.

Pollis is charged with intoxication manslaughter and intoxication assault in the death of 19-year-old SMU student Honor Wallace. Wallace’s friend, who was in the passenger seat, was seriously injured in the September 2023 crash. Intoxication manslaughter carries a maximum sentence of 20 years in prison, and intoxication assault carries up to 10 years.

Pollis likely would have consumed six to 11 standard-sized alcoholic beverages — or three to five larger drinks or doubles — to reach a blood alcohol level that high, Welch said.
