On the morning of Saturday, June 2 police were led to the lifeless body of 4-year-old Matal Zachery Sanchez by his step-grandmother.
Police said his body was found off Highway 211 near Estacada some 25 miles away from his home.
"His body was found in a densely forested area on BLM land, approximately three or four miles southeast of Estacada," said officer Kevin Krebs with the Milwaukie Police Department. "His body was located approximately 75 feet off a roadway."
Matal's mother, Laura Acevedo, lives in the home with Matal's step-grandmother, Christine Coffman. Acevedo initially told police she thought Coffman took Matel on an errand with her.
However, Coffman, 45, claimed she had left without the boy.
On Thursday, police were apparantly suspicious of Coffman's story and decided to seize her car and search for clues Thursday.
The search effort expanded even more Friday, with police executing a search warrant at the family's home, at 6912 SE Daphne Court, and making an appeal to the public for information about the locations visited by a car driven by Coffman on Wednesday.
After three days of police questioning and investigating, police say Coffman confessed to officers late Friday night.
"She was arrested in the death of Matal Sanchez and will make her first court appearance Tuesday," Krebs said.
The Milwaukie Police Department got help from the Federal Bureau of Investigation as well as search and rescue units from Clackamas, Multnomah and Washington Counties, Explorer Scouts and an Oregon Army National Guard helicopter crew during the multi-day search effort and investigation.
Before moving to the Estacada area, police had focused their search on a two-mile radius around Matal's Milwaukie home, based on estimates of how far they thought the boy could have wandered.
During the search for Matal, police said they received some 125 tips and reward money grew to $6,000
