One man is in custody and charged with murder in a double homicide over the weekend that has left a third victim in critical condition.
Carlos Marlo Hernandez-Ventura, 25, of Perry, is charged with two counts of first-degree murder and one count of attempted murder, Perry Police Chief Eric Vaughn said during a news conference Monday afternoon.
Hernandez-Ventura was arrested by police in Morrison, Ill., on a warrant out of Perry. He was arrested without incident, Vaughn said.
The victims were identified as Lourdes Flor De Leak, 34, and her daughter Melany Elizabeth Barraza, 14, both of Perry. A third victim, a 78-year-old man, was taken from the scene by helicopter to Iowa Methodist Medical Center in Des Moines, where he remains in critical condition.

All three subjects suffered multiple lacerations and blunt force trauma, Vaughn said.
"I can't go into details of the scene itself, but it was a pretty traumatic event," he said.
Hernandez-Ventura is currently being held in Whiteside County Jail pending extradition to Dallas County.
According to Vaughn, it was the first homicide in Perry since 1999.
The charges against Hernandez-Ventura stem from an investigation that began at about 8 p.m. Saturday.
Perry officers were notified at that time of a possible deceased person at 802 Sixth St.
When officers arrived on scene they located the three victims.
The victims, as well as the suspect, had all been living at the home at the time, Vaughn said.
It is believed that Leak and the suspect were in a relationship, Vaughn said.
"We believe the mother and the suspect were boyfriend and girlfriend at the time," he said.
The investigation led to a search for a blue Honda Pilot SUV, which was later found by police in Illinois.
"Through our investigation we found it was missing from the scene," Vaughn said. "And then we also found that the subject, the boyfriend, was not located at the scene."
Morrison, Illinois, is more than 240 miles from Perry, east of Clinton, Iowa.
Perry police have not had prior contact with Hernandez-Ventura, Vaughn said.
A motive for the attacks was not offered.
"We're still working on the investigation," Vaughn said. "I can't really comment on that."
Vaughn said the public is not in any danger.
Perry police were assisted by the Dallas County Sheriff's Office and Iowa Division of Criminal Investigation.
