A Colorado jury has rejected the trans-panic defense mounted by the man accused of killing a transgender woman last July.

After less than 3 hours of deliberation, jurors found Allen Ray Andrade, 32, guilty of the first-degree murder of Angie Zapata, an 18-year-old transgender woman formerly known as Justin Zapata.

Andrade, dressed in a fully buttoned latte brown shirt, hung his shaven head as Judge Marcelo Kopcow read the verdict that found him guilty of first-degree murder, bias-motivated crime, aggravated motor vehicle theft in the first degree and identity theft.

“I lost somebody so precious,” said Maria Zapata, Angie's mother. “The only thing he can't take away is the love and memories that I have of my baby.”

Andrade's lawyers concede he killed Angie but attempted to reduce his sentence to second-degree murder or manslaughter with a trans-panic defense.

Transgender rights advocates who have rallied around the Zapata trial hailed the verdict.

“This is a landmark decision,” said Mindy Barton, the legal director of the Gay, Lesbian, Bisexual and Transgender Community Center of Colorado. “Hearing 'guilty on first-degree murder' and 'guilty of bias-motivated crime' was a huge emotional experience for all the family, friends and the supporters of Angie. ... She will not be forgotten.”

Kopcow sentenced Andrade to life in prison without parole, the mandatory sentence for a first-degree murder conviction. The bias-motivated conviction would have added 18 months to his sentence if he would have been found guilty of a lesser offense such as manslaughter.
