The murder of Ingrid Lyne, a single mother of three, has shocked her close-knit Washington neighborhood.
"I almost got sick. I mean, I just talked to her," said neighbor Robert Croner.
"Justice for Ingrid. No one deserves this, no one," said another, Marti Webster.
A neighbor said Lyne's ex-husband reported her missing on Saturday. He said Lyne's purse and phone were in her home.
Friends say Lyne planned to go to a Mariners baseball game Friday night with a date she met online -- 37-year-old John Charlton. When her ex-husband arrived to drop off the kids Saturday morning, she wasn't home, reports CBS News correspondent John Blackstone.
Lyne was reported missing. Hours later, a homeowner called police after finding body parts -- including a foot -- in plastic bags left in a recycling bin just 10 miles from her house.
"We're working closely with the victim's family, all the evidence leads to that particular victim," said Seattle Police Chief Kathleen O'Toole.
Detectives connected the two cases, searched Lyne's home for evidence and identified Charlton as a suspect.
"We used some forensic evidence dealing with telephone calls and cell towers by utilizing those, we were led to a suspect early on," said Seattle Police Assistant Chief Robert Merner.
Neighbors say Charlton has been staying at his home. He was arrested Monday and booked into the King County Jail on suspicion of murder. The investigation is ongoing.
Police found Lyne's missing car late Monday night. They're also looking into whether Charlton could be tied to similar crimes.
"We'll look at other crimes and if any of them seem to be similar in appearance, then we'll continue down that road," Merner said.
