Prosecutors say James Whitewater, 28, of Nampa, shot a fellow Nampa resident in the chest and hit him with a glass beer bottle early Sunday.
And four people one more than police originally sought -- are accused of aiding and abetting the crimes.
Whitewater, his wife Natalie Whitewater and Wayne Canaday had their first court appearances Tuesday afternoon. James Whitewater is held without bond on first-degree murder and aggravated battery charges. A Canyon County magistrate set $1 million bond for each of the other two. Preliminary hearings for all three are set for 8:30 a.m. July 29.
Two more aiding and abetting suspects were apprehended Tuesday. Middleton resident Allison Yancey, 34, has been a suspect since the beginning of the investigation and was tracked to Horseshoe Bend, where she was arrested in connection with the beer-bottle assault, Nampa police report. And a newly identified suspect, Joshua Price Wasserburger, 26, was already in Canyon County custody on an unrelated arrest warrant and now faces a charge of aiding and abetting Martin's murder, police said.
Police called to the Walgreens at 12th Avenue and 7th Street South in Nampa at 2:43 a.m. Sunday found Pedro Martin Jr. on the ground outside the business, which was open at the time of the shooting. Martin, 25, was rushed to the hospital and later died. According to court documents, he was hit with a beer bottle and beaten at a 7th Street South residence and then shot a short time later outside the nearby Walgreens.
Investigators found James Whitewater during a traffic stop conducted by officers searching for him in the area of Purple Sage and Kenridge roads near Middleton. They located Natalie Whitewater and Canaday shortly after, at a residence in the 700 block of Coopers Court in Caldwell.
There were no eyewitnesses to the shooting, Nampa police spokesman Joe Ramirez previously said, but people in the area heard gunshots so the shooting is believed to have occurred just outside or near the store. Police had hoped to obtain surveillance video from the store, Ramirez said Sunday.
Agencies involved in these arrests included: Greater Idaho Fugitive Task Force, Canyon County Sheriffs Office, Nampa Police Department, Caldwell Police Department, Metro Violent Crimes Task Force, and Canyon County Prosecuting Attorneys Office.
