RAHWAY (WABC) -- Police have made an arrest in the killing of a mother who was found strangled in her home in New Jersey.
36-year old Roberto Grillo is charged with murder in the death of 35-year old Yolanda Vega.
She was found dead in her home in Rahway on December 7th.
A family member reportedly witnessed a gunman jump out of a closet and run from the house.
Authorities have not released a motive for the killing.
Grillo was charged with murder late Tuesday night while in custody at Union County Jail, having been arrested by Linden police for allegedly trespassing at the Phillips 66 Bayway Refinery in Linden on the evening of Sunday, December 6 - approximately 90 minutes after Vega was determined to have been killed, and at a location less than half a mile from her home.
Bail for Grillo was set at $2 million.
Vega was born in Salina, Puerto Rico and lived in Newark and Irvington and settled in Rahway 11 years ago. She was an administrative assistant for Dick's Sporting Goods in Edison.
She is not the same Yolanda Vega who is seen on lottery drawings.
