A second person of interest believed to have been at a gas station with three Pasco residents hours before they were killed is being held at the Umatilla County jail.
Cristian R. Hurtado, 23, was recently arrested in Umatilla and is at the jail on $50,000 bail for failing to appear in court on an unspecified charge, jail records show.
Authorities said Hurtado has been questioned in connection with the case and is one of several persons of interest.
Another person of interest, Francisco Javier Resendiz Miranda, told detectives Hurtado was with him and the victims at the gas station Friday night, according to court documents.
Surveillance footage from the Umatilla Pik-A-Pop shows Abigail Torres-Renteria, David Perez-Saucedo and Victoria Torres being "picked up" by several people, including one with a weapon, court documents said. The victims were at the gas station around 10:30 p.m. Friday, just hours before they were found shot to death in a rural cornfield in Benton County.
Miranda, 23, of Umatilla, was originally booked into the jail on kidnapping and conspiracy allegations, but authorities said he is being held on charges unrelated to the homicide investigation.
Sheriff's officials remained mum Thursday on details of the investigation.
The triple homicide is the first in Benton County since 2005.
Torres-Renteria, 23, was almost nine months pregnant when she was shot once in the neck, authorities said. Her unborn baby girl did not survive.
Perez-Saucedo, 22, was shot twice in the head and Torres, 19, was shot once in the neck, authorities said. Torres was found about 15 feet from the other two victims, who were close by each other.
Authorities said they are looking for several people who might have taken part in the shootings or know details about the case.
As detectives worked to gather information, family and friends of the victims gathered at the Kennewick Grocery Outlet parking lot for a car wash.
The car wash was to help raise money for Torres-Renteria's funeral and to honor the other victims, family said. The bodies have not yet been released to family members.
Torres-Renteria's uncle, Jesus Torres, told the Herald that his family, especially Torres-Renteria's twin sister, is struggling to come to terms with her death. He said his family has been looking for answers.
"The answers I want aren't out there yet. I just hope they find whoever did this," he said. "That wasn't the right way to do things."
A second car wash is scheduled for today at the Kennewick Grocery Outlet starting around noon.
Another car wash is scheduled for Saturday starting at 8:30 a.m. in the Subway parking lot on Court Street in Pasco.
