SNOQUALMIE - A crash in Snoqualmie left a 29-year-old son dead and his mother facing charges of felony hit and run after police say she left her son to die.

Debra Whalawitsa is the Director of Administrative Services for the town of Snoqualmie. Early Sunday morning, Washington State Patrol investigators say she lost control of her car along one of the town's scenic, winding roads.

The crash killed Whalawitsa's 29-year-old son Calijah.

But instead of calling 911 and getting help for her son, troopers say she just went home.

"After the collision occurred, she was able to climb from the vehicle," said Trooper Jeff Merrill. "And for some unknown reason, she left the scene; left her son there... went home and didn't return until 10 the next morning."

He added that she never reported the accident. "In fact, it was called in by another motorist later that morning."

After spending the night in jail, Whalawitsa appeared in court Monday facing possible charges of vehicular homicide and felony hit and run. Investigators saw her return to the crash site eight hours later.

She told them she'd come to look for her son.

Investigators tell KOMO 4 News Whalawitsa told them she took the curve at just 35 miles an hour. But, investigators say the way her car hit this curb and catapulted toward the river, they have to think she was speeding.

Whalawitsa told investigators she was taking medication. Investigators believe it's possible she left the scene because she'd been drinking.

But the delay in reporting the crash may make it hard to prove.

In fact, late Monday, the judge said Whalawista can only be held at this time on investigation of felony hit-and-run because there is nothing in the court documents that indicates investigators are anywhere near being able to prove that she might have been drinking that night. She does admit to taking medication, but there's no proof yet of alcohol.
