Christopher Lamar's blood alcohol level was three times the legal limit when he slammed into the rear of a car on Interstate 10 last year.
Jessica Rodriguez, 28, and her daughter, Kaylee Flores, 10, were in Rodriguez’s car, stopped in the breakdown lane with a flat tire.
Both were killed instantly.
Lamar was booked on an intoxication manslaughter charge and later charged with felony murder since this was his third DWI arrest.
That is a felony and carries a significantly more serious punishment than intoxication manslaughter.
On Thursday, a jury found him guilty of felony murder.
On Friday, during the punishment phase of his trial, several police officers testified concerning Lamar’s previous arrests.
“His speech was slow and slurred, he had red eyes, could not maintain his balance and his breath smelled of alcohol,” said Texas DPS Trooper David Villanueva.
Villanueva had stopped Lamar for speeding on Interstate 10 near Seguin in 2006.
He arrested Lamar for driving while intoxicated.
He was also arrested for DWI in College Station in 2008.
Lamar is facing a maximum sentence of life in prison following Thursday’s conviction. Had he been tried for intoxication manslaughter, the maximum sentence was 20 years in prison.
Closing arguments followed by jury deliberations are set for Monday morning in Judge Melisa Skinner’s 290th District Court.
