A 28-year-old woman is accused of second-degree manslaughter after authorities say she abandoned her parents when she crashed the car they were traveling in near Gresham on Sept. 10 and her father later died.

Alma Santiago was arrested Thursday and booked into the Multnomah County jail on suspicion of driving under the influence of intoxicants, failure to perform the duties of a driver and reckless driving. Maritza Montelongo-Sanchez, a 25-year-old friend of Santiago, was also arrested Thursday and accused of hindering prosecution and evidence tampering.

Montelongo-Sanchez is accused of driving Santiago away from the scene after she witnessed the crash and later taking Santiago's bloody clothes, according to a probable cause affidavit.

Miguel Alejo Santiago sustained serious head injuries from the crash and died at OHSU Hospital three days later, the affidavit said.

Emergency responders were called to the crash scene around 1:30 a.m. in the 16500 block of Southeast Foster Road and found Miguel Alejo Santiago and his wife there, the affidavit said. She sustained apparent minor injuries and wasn't taken to a hospital. The 2007 Kia Rio they were in was on the side of the road upside down on its top.

The wife told Multnomah County deputies at the scene that her husband was driving them home after they left a party and crashed, the affidavit said.

A deputy questioned her version of events because the driver's seat appeared to be too close to the steering wheel for Miguel Alejo Santiago's size and height and the majority of the blood in the car appear to be in the back seat, the affidavit said. There was also a phone with a rose-colored covering and a purse inside the car that the wife claimed didn't belong to her.

Investigators determined the car was registered to Alma Santiago, and other witnesses reported she had been the driver, but left before police and paramedics arrived, according to the court papers.

Santiago was interviewed by investigators that next day and she cried as she was questioned. She admitted to drinking "a couple of shots and some beers" at a family gathering with her parents and losing control of the Kia after driving too fast. She said her father was in the back seat and her mother was in the front passenger seat, the affidavit said.

Montelongo-Sanchez had been driving behind Santiago when the crash occurred, the affidavit said. Santiago told investigators that she "slid out of her car" after the crash, got into Montelongo-Sanchez's car and left, according to the court papers.

Montelongo-Sanchez told police she saw Santiago drinking alcohol at the party, witnessed the crash and admitted to driving them both away, the affidavit said. They first drove to another friend's home, but were turned away because of the blood on Santiago's clothes.

Santiago was then driven to Montelongo-Sanchez's apartment where the friend put Santiago's clothes into bags, the affidavit said. Investigators found dried blood on the passenger's side of Montelongo-Sanchez's car.
