James Dixon, who pleaded guilty earlier this month to killing Islan Nettles in 2013 because she was transgender, was sentenced today to 12 years in prison. Prosecutors had originally asked for 17 years, and at today's sentencing, Nettles's family pleaded with the court, saying that 12 years is not enough.

"For him to only get 12 years—that’s not right," Nettles's 19-year-old sister, Sky Nettles, said today, adding, "My sister couldn't even speak. She didn't look like herself...She looked like a monster."

Nettles, who worked as an assistant at a fashion company, died in 2013 after she was brutally beaten in Harlem. Police initially charged another man for the attack, but dropped the charges and, over a year later, arrested Dixon on charges of manslaughter and felony assault.

According to Dixon's guilty plea and court records, Dixon, 25, along with at least six other young men, encountered Nettles and two other trans women on Eighth Avenue between 147th and 148th Streets on August 17th, 2013. Dixon hit Nettles and her head struck the pavement, after which he hit her again, causing a traumatic brain injury, the Manhattan District Attorney's office said when Dixon pleaded guilty.

Dixon reportedly admitted to attacking Nettles after realizing that she was transgender. During a recorded questioning, he said that he "just didn't want to be fooled." Known as the "trans panic" defense, this tactic was banned in California in 2014.

When offering a statement today in court, Nettles's mother addressed Dixon directly, Mic reports.

"I hope you die," Delores Nettles said. "I will hate you for the rest of my life for taking something that belonged to me. Your mother can see you every day and say 'I love you.' I can't hear that. I'm subjected to seeing my child on a mantle...I had eight children and never thought that I'd have to bury one."

When Dixon's plea deal was announced, Manhattan DA Cyrus Vance said that "members of the transgender community are far too often the targets of violent crime. I hope that this conviction provides some comfort to Ms. Nettles’ family and friends, and affirms my office’s commitment to protecting members of the LGBTQ community." However, some advocates say that this is far from the case, as Lourdes Hunter, director of the TransWomen of Color Collective, told Rewire:

"This is not a win for the trans community...James Dixon going to jail will not stop trans murders, it will not bring Islan Nettles back, it will not bring peace to Delores Nettles, who for many years sat in anguish as the murderer of her child roamed the streets due to the negligence of the New York Police Department and the New York District Attorney."

Nearly twice as many transgender and gender-nonconforming people were killed in 2015 as in 2014, according to Rewire, and the majority were people of color. Just this past Saturday, Keyonna Blakeney, a 22-year-old black trans woman, was killed in Maryland.

Dixon reportedly showed no remorse at his sentencing, and declined to make any statement before Justice Daniel P. Conviser sentenced him to 12 years.

"He can go home after those 12 years and see his family," Nettles's mother told the court. "It's not fair."
