Oliveras resided in the Hyde Park area of Boston, Massachusetts in 2006. His ex-girlfriend, with whom he was on friendly terms, sent him money to take a bus to Portland, Maine to visit her on August 31. Oliveras was last seen at his ex-girlfriend's workplace on September 3, 2006. She is an exotic dancer at the Platinum Plus nightclub on Riverside Street. Oliveras was asked to leave, as he was discouraging men from tipping his friend. He walked out of the club without incident and was last seen in the parking lot at 1:00 a.m., accompanied by an unidentified Caucasian male.

At the time of his disappearance, Oliveras had no car, no cellular phone, no luggage, no bank account and very little money. Authorities believe he probably did not leave of his own accord. He was unemployed at the time he went missing. Oliveras is the father of two children. His loved ones stated it is uncharacteristic of him to leave without warning. Oliveras's ex-girlfriend has been cooperative in the investigation. His case remains unsolved.
