Sarah Hatfield, Thornton Mother, Accused Of Abandoning Children At Gas Station

Sarah Hatfield, a 25-year-old Thornton, Colo. mother, was arrested Saturday for allegedly abandoning her two young sons in a van at a gas station parking lot -- police found her wallet and keys in the van and found Hatfield nearly 12 miles away, hours later.

9News reports that gas station employees noticed the gold van around 1:30 p.m. on Saturday and didn't think much of it until an hour went by and the van was still parked in the lot. After a couple of hours, a gas station employee decided to check out the van and found the 2-year-old and 4-year-old boys still in their car seats, along with her car keys, purse and cell phone.

About ten hours after Hatfield went missing, she turned up at National Jewish Hospital in Denver -- a security guard called the police when he had found Hatfield near the hospital around 11:45 p.m. The hospital is nearly 12 miles away from the gas station where the van was parked, according to Fox31.

How the woman got to the hospital still remains a mystery because Hatfield's husband Matt told the police and 7News that Sarah has no recollection of the hours she went missing. "This is totally out of character," Matt Hatfield told 7News and went on to say that his wife "has never been arrested, never touched illegal drugs -- nothing about this makes any sense to anyone who knows her."

Early toxicology tests confirmed Matt's defense of his wife -- no illegal drugs were found in Sarah's system, according to 7News.

Sarah Hatfield is undergoing tests at Denver Health and her husband spoke to Fox31 saying that preliminary tests suggest that his wife may have suffered from a seizure which triggered a kind of amnesia.

Sarah appeared to have no injuries and did not appear disoriented when the police arrested her, but she complained of soreness all over body which left family members wondering if she had walked all the way from the Thornton gas station to the Denver hospital.

Sarah Hatfield remains in custody at Adams County Detention Center and faces child abuse charges.
