Autopsy reports show both children suffered gunshot wounds and cuts to the neck before they died. Potentially toxic levels of doxylamine, a drug commonly found in sleeping pills and allergy medications, were detected in the blood of Ellie and her brother Aden.
Nine-year-old Ellie died from a gunshot wound to the head and cuts to her neck, according to an autopsy report written by forensic pathologist Dr. Megan Kliesner.
Aden died from a gunshot wound and also suffered neck injuries. High levels of doxylamine were found in both children.

Singer also allegedly injured herself and her 11-year-old daughter, who has not been identified, before calling 911 and reporting the attack as a robbery in the early morning hours of December 19.
Police responded to an apartment complex and found her and her 11-year-old daughter, who was still alive, lying next to the bodies of her other daughter and her son.
Colorado Springs police investigators later determined that the robbery report was unfounded, which It came the same day a judge ordered police to locate the children after she failed to leave them with their father.
Court records show that Singler, presiding over a hearing scheduled for Dec. 20, who was representing herself, went to a public library and filed a motion requesting that that day’s hearing continue.
In the motion she claims that an unknown person broke into her residence on December 18 and attacked her and her three children.
He stated that he was weak, in a lot of pain, and was unable to call 911 until midnight on December 19.
Detectives, who were looking for her for alleged murder, attempted murder and child abuse, said they had last seen her on Dec. 23 and believed she had fled the state.

Wentz claimed that Singler made accusations of domestic violence and child abuse against him, which a Larimer County court found to be unfounded, and that Wentz was not considered a threat to children.
Singler was involved in a long custody battle with her ex-husband Wentz, who issued a press release following the alleged murders and revealed the names of his two deceased children.
She claimed the incident is related to her divorce from Singler, which dates back to September 2018.
Wentz said Singler made accusations of domestic violence and child abuse against him, which a Larimer County court found to be unfounded, and that Wentz was not considered a threat to children.
However, the tense battle continued well into 2023, when Singler obtained a Temporary Order of Protection in El Paso County against Wentz after she alleged that he had pulled a knife on her.
Wentz denied the charge, but the order was stayed until Jan. 24 and an appeal hearing was scheduled.
Singler filed another emergency motion in county court on Nov. 17 to try to restrict Wentz’s parenting time based on those same allegations, but the court vacated the order after finding there was no imminent threat.
The Larimer County Court even ordered Singler to pay Wentz’s legal bills and give him recovery time to cover what he had lost under the order.
Singler did not comply with those directives and did not bring the children to Wentz on the scheduled exchange date of Dec. 16, Wentz said.
Both he and his legal representatives tried to contact his ex-wife but received no response.
Wentz was granted an emergency motion for police assistance in enforcing parenting time on Dec. 18 and scheduled a status conference for two days later, ordering Singler to appear with the children.
But by December 19, two of the three children were dead. He said he has cooperated fully with the police investigation into the murders.
Colorado Springs police arrived at the scene and spoke with Wentz, who denied all allegations.
A Colorado Springs Police Department spokesperson said at the time that the 11-year-old girl was recovering from her injuries and was being treated. It is unknown where she is being treated or who is taking care of her.
