A Livermore couple linked to a appeared in Pleasanton court on Monday.
Evan Aviles, 22, and his girlfriend, Lexie Hutson, 23, .
The two, both dressed in yellow inmate suits, appeared Monday afternoon at Judge Hugh Walker's courtroom in the Gale-Schenone Hall of Justice.
Hutson broke down in tears when Walker read a court complaint that said she and Aviles are responsible for the death of injured in the May 21, 2011 apartment explosion on Silver Oaks Way.
Lom, who police said was inside the apartment with Hutson and Aviles during the explosion, succumbed to his burn injuries five days later.
A police report said Lom suffered burns to 90 percent of his body from the explosion caused by the manufacturing of hashish oil.
Evidence showed Aviles, Hutson and Lom were actively manufacturing hashish oil and used highly flammable liquid butane to extract the oil, police said.
While engaged in the manufacturing of the controlled substance, an unknown amount of highly flammable gas pooled on the floor, which led to the explosion, according to a police release.
In addition, an investigation found a how-to video on manufacturing hashish oil downloaded from the Internet on a computer found inside the apartment, according to a police report. Internet searches of "hash oil," "hash" and "butane" were also found on the computer, a police report said.
"I believe Evan and Hutson acted in conscious disregard for human life by participating in the dangerous manufacturing of hashish oil in an unventilated apartment, which resulted in the unlawful killing of Lom," Livermore Police Detective John Reynolds said in a police report. "They knew, or should have known, the manufacturing process using butane extraction was dangerous to human life."
Both Hutson and Aviles at Monday's court appearance requested to see a public defender. Walker ordered them to return to court at 2 p.m. Wednesday for a plea hearing.
Hutson and Aviles are being held at Santa Rita Jail in Dublin with no bail.
