A convicted murdered is now facing new charges in an unsolved 2012 homicide in Bushwick. Henry Pacheco pleaded not guilty to murder, arson and petit larceny at Kings County Supreme Court Friday. Prosecutors said the 44-year-old is tied to the 2012 murder of 25 year-old Lorena Escalera, whose stage name was Lorena Xtravaganza. The FDNY responded to a fire at her apartment on Furman Avenue that they deemed suspicious. Their investigation found that Escalera was dead before that fire started and that the fire originated in her bed. Prosecutors said surveillance video shows Pacheco entering the apartment and leaving as the fire started, and that cellphone records tie Pacheco to the case. “Ms. Escalera came to Brooklyn to pursue her dreams of becoming a performer, but her life was brutally snuffed out instead when she was only 25," said Brooklyn District Attorney Eric Gonzalez in a statement. "The quest for justice lasted over a decade but today we are able to charge her alleged killer who we’ll now seek to hold fully responsible for this killing and the arson that put many other lives at risk. I hope that Ms. Escalera’s loved ones and friends will find a measure of solace knowing that this tragic murder has now been solved. In Brooklyn, we protect everyone, no matter who they are, who they love or where they came from.” Pacheco is already serving a 20 years to life sentence for an unrelated homicide in 2017, and prosecutors said Pacheco's rap sheet also includes possession of controlled substance, attempted burglaries and four prior violent felony convictions. Pacheco will remain in custody as he serves his prison sentence, his next court date is Feb. 19.
