Roberto Aguirre Ramirez

OREM — A housemate of a man accused of stabbing his wife to death in the couple's Orem home witnessed parts of the bloody incident, court documents say.

On the morning of Jan. 4, Roberto Aguirre Ramirez, 27, and his wife, Norma Leticia Villalobos-Guzman, 36, both covered in blood, walked out of their bedroom and past the housemate, who was preparing a bottle for his infant, according to an affidavit filed in 4th District Court.

Ramirez stood next to his wife, who was seated on the ground, and said, "You and I are going to die today," the affidavit says.

There is no indication of what led to the domestic dispute that ended in Villalobos-Guzman's death later that day.

Ramirez was released from a hospital and jailed Sunday for investigation of murder, possession of a dangerous weapon by a restricted person, aggravated assault in the presence of a child and obstruction of justice.

His bail is set at $500,000 cash.

The police affidavit describes the scene officers found after the housemate's wife called police. There were "multiple pools of blood and smears of blood" on the floor leading to two closed doors.

Approaching one of the doors, officers heard a female voice say "come in." They entered the bedroom and saw Villalobos-Guzman lying in blood on the bed. She extended her arms and said, "Help me," the affidavit says.

Ramirez was on the ground bleeding and breathing with difficulty.

The housemate told police that he had tried to calm Ramirez by patting his arm after Ramirez said the couple would die. Ramirez then stabbed himself on the right side of the chest and slit his wrist, according to the affidavit.

Ramirez admitted to police that he was in the country illegally in December 2008 when he was arrested in a drug bust at his Orem apartment, court documents say. He pleaded guilty to several drug and weapon charges and was sentenced in April to 210 days in jail, with credit for 111 days served.

However, the affidavit says Ramirez was deported to Mexico in May. Neighbors have said Ramirez and his wife moved into the house at 536 E. Sage Circle in October.

His "presence in Utah constitutes aggravated re-entry," the affidavit says. Another neighbor has said U.S. Immigration and Customs Enforcement agents had removed several people from the house within the past two months.

Villalobos-Guzman's daughter told police Ramirez hit her mother with his fist and with a chair in recent months, according to the affidavit. He had also threatened to kill his wife on a trip to California, her brother told police.

Police have said the victim was also in the country illegally and used many aliases, which led to confusion in identifying her.
