LOS ANGELES — A California woman could face up to seven years behind bars on a slew of charges filed Tuesday after authorities say surveillance video showed her casually tossing a bag of 3-day-old puppies into a trash can on a sweltering day.

Deborah Sue Culwell, 54, was charged with seven felony counts of injuring the palm-sized puppies and seven misdemeanor counts of abandoning them.

The puppies' mother may have been among 38 dogs found inside Culwell's home following her arrest, and authorities were determining whether a reunion would be possible, according to the Riverside County Department of Animal Services.

Though most of the 38 dogs in the home appeared to be "somewhat healthy," some were aggressive or fearful, the agency said, adding that the house was in a state of disrepair.

The case drew national attention after surveillance video showed a woman dropping a bag with the puppies into the trash Thursday before taking off in a Jeep Wrangler. Authorities posted the video to social media to help track her down, but they ultimately found Culwell based on a search of the Jeep's plate number.

It's unclear if Culwell has an attorney. Her number is unlisted.

Video of the arrest shows Culwell being led from her home as a reporter with KNBC-TV peppers her with questions such as, "Why would you throw those puppies away like trash?" and "Do you have anything to say about your actions?"

A handcuffed Culwell remained silent as she was taken from her home in Coachella, a desert city about 130 miles (210 kilometers) east of Los Angeles.

The five male and two female puppies, believed to be terrier mixes, survived after spending about an hour inside a plastic bag in the dumpster, which was open. A man heard them crying and took the puppies to a nearby store, where an employee called authorities.

"If not for the good Samaritan's actions, the puppies may not have survived much longer," the animal services agency said in a news release, adding that temperatures in the area had reached the mid-90s on Thursday.

The pups were dehydrated and malnourished and are being cared for by a volunteer who is bottle-feeding them. The volunteer, Noni Boen, posted a video of the puppies cuddling and mewling on Monday, saying they had just been fed and returned to their nap pile.

"There is no excuse for dumping puppies," Chris Mayer, commander of animal services, said in a statement. "Especially in today's age when we or other shelters would be willing to get these animals to foster parents or rescue partners. This was a shameful act."
