Kassandra Cantrell

Mom-to-be vanishes a day before sonogram. Her mother suspects baby’s father, who reportedly has a girlfriend.

A pregnant Washington woman was looking forward to her first sonogram, excited to see whether she was carrying twins, when she mysteriously vanished on August 25.

KIRO 7 reports that Kassanndra Cantrell, 33, of Parkland, ended up missing her sonogram appointment and has not been seen or heard from. There’s also been no activity on her social media accounts and none of her debit or credit cards have been used.

Authorities said there has been no activity on her cellphone, but it last pinged at Vashon Island.

As CrimeOnline previously reported, family members told Q13Fox  that Cantrell was excited about her pregnancy and would never have missed her first ultrasound appointment.

“She wouldn’t have missed it for the world, it doesn’t make any sense for her to be gone at all,” said Marie Smith, Cantrell’s mother.

Cantrell lives with her mother in Parkland, an unincorporated suburb just south of Tacoma.

Smith said she last saw her daughter early morning on August 25 as she (the mother) headed off to work. About an hour later, a security camera caught Cantrell driving away in her white 2014 Mazda 3.

Smith said her daughter had intended to go grocery shopping at some point, but she doesn’t think that’s where she was heading when she left Tuesday morning. There have been no records of Cantrell stopping at a grocery store.

“She wouldn’t just go dark on all her social platforms,” Smith added.

Police found Cantrell’s Mazda just before midnight on August 27, parked underneath the overpass to Highway 705, a few blocks from the Tacoma Dome. Authorities have asked nearby businesses to check security footage for any sightings of Cantrell or her car.

Smith now worries that the father of the baby may be somehow involved, although authorities have not named him as a suspect.

“And I wouldn’t have suspected him if he wasn’t the father. But he has a girlfriend so I don’t know what that might, you know, what that might have triggered.”

Search teams scoured Defiance Park on Sunday for any signs of Cantrell. The search resumed Monday morning.

“This is way out of character for her so we’re worried,” said Ed Troyer, spokeswoman for the Pierce County Sheriff’s Department, The News Tribune reports.

Cantrell is described as a white female who stands 5-feet-7-inches tall and weighs around 180 pounds. She has brown hair and blue eyes.

Anyone with information on her whereabouts is urged to contact 911 immediately.
