RENTON, Wash. (KOIN) – Human remains found in a recycling bin have been tentatively identified as a Renton mom who went missing after a date Friday night.

Ingrid Lyne, 40, a Seattle hospital nurse and mother of 3, wasn’t seen or heard from after going on a date to the Seattle Mariner’s home opener, police said.

Lyne’s ex-husband reported her missing on Saturday, a neighbor said, the same daySeattle Police Dept. found “fresh” body parts in a homeowner’s trash bin.

John Robert Charlton, 37, was arrested in Snohomish County Monday in connection with the dumped body parts. He was booked into jail on investigation of homicide.

Family members tell KIRO Charlton is the man who took Lyne on a date.

Police say they have no reason to question that Lyne is the victim, but they can’t confirm her identity without the medical examiner’s report.

Lyne’s car was found late Monday night in downtown Seattle, police said.

About 40% of the single population uses some form of online dating. While the websites and apps are convenient, they can be dangerous if you don’t take the proper precautions.

In Lyne’s case, she reportedly did all the right things: she told friends and family where she was and set her date for a public place. It’s unclear what led to her killing.

Women’s defense instructor Joe Heller tells KOIN 6 News you can never be too prepared when meeting someone you don’t know well, regardless of where you met.

“Your safety is the most important thing,” Heller said. “So if you trust somebody after a couple of hours to go home with them, anything could happen.”

He has tips for those meeting someone from a dating app or the Internet in general.

“Awareness is paramount to surviving any situation,” Heller said. “Have the planned designation time for leaving, you can always continue the date on another day.”

Carrying a weapon, whether it be a gun or something less lethal like pepper spray, is an option, but only if you know how to properly use it.

“Practice taking it in and out of your clothes so you know immediately where it is and then train with that object,” Heller said. “Practice with the mace in your garage… you don’t even know what it’s like to fire it for the first time unless you have experience.”
