article: The owner of the East Village building that blew up last week and left two dead people could yet face criminal charges, it has emerged. Nicholas Figueroa, 23, and Moises Locon, 26, both died when the Manhattan apartment building collapsed last Thursday following a massive blast. Investigators have now shifted their focus to what caused the explosion, with suggestions someone may have improperly tapped a gas line serving one of the buildings. Scroll down for video .

In August utility workers discovered the gas line to the restaurant had been illegally tapped, it has emerged . Nicholas Figueroa (left) was killed in the explosion while on a date, while Moises Lucon (right) worked at the restaurant and was identified yesterday as the second victim . The New York Post reported an investigation is now underway into possible gas tapping, with a criminal case expanded to include Haria Hrynenko, the building's landlord. Sources told the paper possible charges include second-degree manslaughter and reckless endangerment. The explosion at 121 Second Avenue in the East Village set alight the property, while its neighboring buildings, 119, 123 and 125 Second Avenue, were also engulfed before all three buildings completely collapsed to the ground, leaving a massive hole on the corner of the block at 7th Street. The medical examiner yesterday confirmed the identity of the second victim using DNA analysis as that of restaurant worker Moises Locon. He had been working six days a week and his family said during his free time he enjoyed taking his nephew to a Queens park. He was reported missing after the explosion and his body found days later. Another 22 people were injured. Meanwhile, in August, utility workers had discovered that the gas line to the restaurant had been illegally tapped, according to Consolidated Edison.

The discovery led Con Edison to shut down gas service to the building for about 10 days while the building owner made repairs. Gas service was restored after the utility deemed it safe, the utility said. Inspectors from Con Ed visited that building about an hour before last week's explosion and determined work to upgrade gas service didn't pass inspection, locking the line to ensure it wouldn't be used and then leaving, it was claimed. The work underway was to put in a bigger line to serve the entire building, Con Ed President Craig Ivey said. Fifteen minutes later, the sushi restaurant's owner smelled gas and called the landlord, who called the general contractor, Chief of Detectives Robert Boyce said. No one called emergency dispatch or Con Ed. The contractor, Dilber Kukic, and the owner's son went into the basement and opened a door, and then the explosion happened, burning their faces, Boyce said. Kukic - who's facing unrelated charges of bribing an undercover investigator posing as a housing inspector - declined through his lawyer to comment on the circumstances surrounding the explosion. Firefighters continued to blast water at pockets of flames among the rubble the following day . Photographs taken on Friday showed three buildings entirely collapsed following the explosion . The city's mayor said it could take up to a week for the rubble to be cleared from the explosion site .
