The children - Conner Snyder, 8, and Brinley Snyder, 4 - were both unresponsive and hanging from the same dog leash, the Reading Eagle reported.
Berks County prosecutors announced Lisa Snyder's arrest Monday.
A single mother was charged on Monday with murder in the hanging deaths of her young son and daughter in the basement of the family's home in rural Pennsylvania two months ago.
The dispatcher can be heard informing the officers of the situation, saying that the mother told them Conner was "bullied" at school and "made threats of doing this" before.
"This is a horrific and tragic incident", said Berks County District Attorney John T. Adams during a news conference on Monday. Snyder was also charged with sexual intercourse with an animal, tampering with evidence, and animal cruelty. As you will recall, Connor was only eight years of age.
Investigators in October said Lisa Snyder described finding them in the basement hanging by a cord, possibly a dog leash, from the rafters.
"I would agree that we all may think that a mother of children who are found hanging would make every effort possible to save them", Adams said. Other alleged searches included "I nearly got away with it best episodes" and "hanging yourself"; the latter search happened on September 22, per court records, and resulted in a visit to a website on the topic.
The court papers also quoted authorities as saying that Snyder also conducted searches for "how long to die" from carbon monoxide and for "almost got away with it", a reference to a true crime television series on the cable channel Investigation Discovery, the paper reported.
Lisa Snyder was arrested a short time before 9:30 a.m.at her home, and was being arraigned on murder, child endangerment, and related charges before a district judge, Pennsylvania State Police Trooper David Beohm said in a news release.
Adams said detectives interviewed relatives, school officials, and Conner's classmates, finding no evidence the boy ever complained of being bullied or had ever expressed a suicidal thought.
