LI illegal migrant’s motive for stabbing upstairs neighbor 50 times revealed

A deranged illegal immigrant stabbed his upstairs neighbor 50 times inside their Long Island apartment building – all because her high heels made too much noise, prosecutors said Tuesday as he pleaded not guilty to slaughtering two women

Rony Yahir Alvarenga Rivera, 22, allegedly told cops that he first hacked neighbor Eddy Raquel Hernandez Castillo to death on April 30 because the racket she made drove him nuts.

“He told her he was annoyed by the noise that she was making, wearing high heels and talking loudly on the phone,” Nassau County District Attorney Anne Donnelly told reporters. “When he was arrested, his clothes were full of blood.”

Rivera, an immigrant from El Salvador, entered the US illegally as an unaccompanied 12-year-old in 2016, according to federal authorities.

Nassau prosecutors said the accused killer later told detectives that he knew he would get caught after the grisly slashing – so he planned a second fatal attack.

Shortly after midnight on May 1, Rivera allegedly drove to his job at a Lynbrook Wendy’s and waited outside by a dumpster for nearly a half hour before he ambushed coworker Ana Maria de Aguila Cordova, a 42-year-old mother of three, when she came out to take out the trash.

Rivera had a “beef” with Corodova and felt “disrespected” by her, and stabbed her upwards of 30 times during the bloody assault, the DA’s office said.

The maniac then called the cops on himself from an area 7-Eleven, police said.

Rivera, 22, allegedly confessed to both slayings, but pleaded not guilty as he was arraigned on murder and other charges in Nassau County court on Tuesday.
