A former San Antonio Police officer serving a 15-year manslaughter sentence for the death of a colleague has lost his appeal.

The 4th Court of Appeals issued an opinion Wednesday upholding the 2010 conviction of David Seaton, 46, who killed Officer Robert Davis and seriously injured a motorist in November 2008 while speeding to a low-priority shoplifting call at speeds of about 100 mph without his overhead lights or sirens.

Seaton's attorneys had argued to the appellate panel that there was insufficient evidence for his conviction and that he deserved a new trial because of jury misconduct. Seaton's attorneys made a similarly unsuccessful request for new trial to state District Judge Sid Harle two months after the conviction, suggesting that the jury forewoman had a political agenda revealed in blog posts after the trial.

The forewoman denied any wrongdoing or ill intent, and the appellate panel agreed.
