Jorge Rios -- who was deported from the U.S. in 2003 and then again a year later -- has been charged with murder, felony murder, aggravated sexual assault and kidnapping.
Carolina Cano, a 45-year-old nanny from Jersey City, was killed March 24 as she was going for a run in Lincoln Park. Her body was found in a lake at the park. Marks on her body indicate she had been strangled.
Rios was arrested a week later. He is an undocumented Honduran immigrant in the United States illegally.
Hundreds held a public memorial for Cano, who was originally from Peru who was described by a member of her congregation as "the sweetest person I knew."
Rios is being held at the Hudson County jail in Kearny.
