Two brothers went to an anime convention last weekend after the older one shot and killed their parents in their home in San Jose, Calif., court documents allege.

Prosecutors today charged Hasib bin Golamrabbi, 22, and Omar Golamrabbi, 17, with two counts each of murder, the Santa Clara County district attorney’s office said. Omar Golamrabbi was charged as an adult, prosecutors said.

Hasib bin Golamrabbi admitted to shooting his father multiple times in their garage “because a stranger whom he could not name had assaulted him in the home (and) had told him to do that,” according to a court document released by the district attorney’s office. He said another person had shot his mother multiple times.

Omar Golamrabbi told investigators that he had been inside their home when his older brother killed his parents but didn’t mention the presence of another person, according to the court document.

After Hasib bin Golamrabbi killed his father, he asked his brother to close the curtain, Omar told investigators. Hasib then killed his mother, according to court documents.

Before leaving for to the anime convention in Oakland Saturday morning, Omar Golamrabbi said he checked to “make sure that blood was not seeping out from inside the garage.”

Investigators said the brothers were later seen at Kraken Con “behaving normally.”

On Sunday afternoon, relatives tried to reach Shamima Rabbi, 57, and her husband, Golam Rabbi, 59. Golam Rabbi apparently hadn’t shown up for work. The relatives then talked to the siblings and asked them to come home, but they did not show up.

After waiting for several hours, the relatives entered the home, where they found multiple writings and one of the victims.

Police were called and found the other body.

Court documents do not reveal what the messages that investigators found on the walls and floor had said. Investigators matched writings at the crime scene to notebooks found in the brothers’ bedrooms, according to court documents.

One of the writings had specific characteristics “consistent with Omar’s writing,” an investigator said in court documents.

The younger brother was found about two miles from their family home that Sunday. Police tried to contact the older brother, but he had turned off his cellphone, according to court documents. He was eventually found and arrested in Tracy, Calif., on Wednesday.

In a jail interview, Hasib bin Golamrabbi told the San Francisco Chronicle that his teenage sibling was not involved in the killings and that more information would be revealed during the trial.

“I want everyone to know what happened, but I can’t say anything without a lawyer,” he said.
