On Sept. 12 around 3:58 p.m., officers were tasked with locating a driver suspected of being under the influence, Longview police said in a statement.
A person had called 911 to report that a woman was driving a Longview School Bus District bus and "appeared to be intoxicated," police said.
In the 911 call, a child tells the dispatcher that he's making the call instead of his mother because she does not speak English.
"Ummm, yea, hello. ... We just got off the bus -- me and my friend. And on bus 8 … the bus driver, Catherine, she was drunk," a child can be heard telling the 911 dispatcher in audio released to ABC News. "She passed three red lights and she got on the side road by the 76. And there's still kids on there. And I was telling my friend to get off with me -- and his sister -- but the bus driver wouldn't let him."
The child tells the dispatcher that the bus driver was "wobbling."
"Her eyes, you can tell, she was drunk," he says.
"Officers smelled an obvious odor of intoxicants coming from Maccarone," the police statement said.
Maccarone was arrested for allegedly driving under the influence. There were no children on the bus at the time of the arrest, police said, but she had completed two afternoon bus routes. Police said they were trying to identify the passengers on that bus.
The Longview School District said Friday that Maccarone had been working as a bus driver for one year and that, to its knowledge, she had not been reported or investigated for similar alleged incidents in the past.
Rick Parrish, the district's communications coordinator, told ABC News Friday that up to 90 children may have been on the bus that day with Maccarone. He said that he had spoken to the student who made the 911 call as well as the student's parents.
Parrish said Maccarone was on paid leave while an investigation is underway.
"Depending on how any given investigation unfolds, the pay status could change," Parrish said.
Maccarone was booked into the Cowlitz County jail on a DUI and reckless endangerment. She paid bond and was due back in court on Oct. 15, jail officials said. ABC News' attempts to reach Maccarone's public defender were not successful.
Police said that additional charges were possible as they continued their investigation and that the district was working with the police.
"At Longview Public Schools safety and security of our students and staff is a top priority," Parrish said in a statement Friday. "The district will complete an investigation into the incident very soon and notify the public of the outcome. In the meantime, an initial review of transportation processes and procedures has taken place and resulted in changes to the bus key check out process. Additionally, the district has invited a state Department of Education transportation manager to review our transportation processes and provide feedback from improvement."
