(CNN)The body of 5-year-old Eliza Talal was found Wednesday after she went missing from her Pennsylvania home at the height of the storm a day earlier, Towamencin Township Police Chief Tim Dickinson said.
Officials found the body of a 5-year-old girl who went missing as Isaias pounded Northeast
Towamencin Township, in the southeastern part of the state, felt the powerful effects of Isaias as the storm barreled through the East Coast earlier this week. In its wake, the storm left heavy flooding, damage and widespread power outages, prompting at least two governors to declare states of emergency. On Thursday morning, nearly two million people were still without power across the Northeast, according to poweroutage.us.
Eliza, who the chief said had autism and was reportedly nonverbal, was last seen around noon on Tuesday before she walked away from her home, which backs into a creek, the chief said.
"We believe based on the circumstances, that she left the house and somehow went into the water," Dickinson said.
Authorities and volunteers conducted an extensive search.
"I can tell you that these police officers here, and first responders, and community members, searched tirelessly," the chief, who was visibly emotional said. "Our prayers go out to her family, who have suffered a terrible loss. Not the result that we were certainly hoping for."
Eliza is one of at least seven people who died during the storm this week.
