NM Supreme Court: Collier Can Be Tried Again in Horse's Death

Prosecutor Seeks Justice in Horse’s Training Death

A horse trainer, accused of causing the death of a thoroughbred seven years ago, will stand trial for a third time. Prosecutors in Doña Ana County reinstated the case against Greg Collier.
The move comes months after the New Mexico Supreme Court ruled that Collier, of Texas, can be tried again without violating his constitutional rights. The Supreme Court, in a 5-0 decision, reversed an earlier Court of Appeals ruling.
Prosecutors allege Collier used violent and excessive techniques to train a yearling thoroughbred. By the state’s account, Collier was “humiliated” over his lack of progress in developing the horse named Cowboy as a racehorse. Collier allegedly attacked the colt, striking him repeatedly for about three hours. The colt reportedly died from internal injuries the next day.
Governor Susana Martinez was the prosecuting attorney when the case began. District attorney Mark D’Antonio takes the reins now after being sworn into office in December 2012.
Collier initially stood trial in 2008 for extreme cruelty to animals. Jurors could not agree on a verdict, and the judge declared a mistrial.
He was later acquitted of felony animal cruelty in 2009 after the jury deadlocked 11-1 in favor of a misdemeanor conviction. A unanimous verdict was needed.
Collier’s trial is scheduled for February 12, 2014.
The case was dismissed September 2014.
