HAMMOND - On Thursday of last week, Ashling Mayo reported to Tangipahoa Parish Sheriff's deputies that she had allegedly been assaulted by Hammond police officer Corey Bergeron.

While investigating the incident, deputies say they located evidence related to a prior situation involving Mayo, which led to Bergeron's arrest on Monday.

"She's basically on the roller coaster of emotions that come with domestic violence, and you know, trying to leave your abuser and get out of an abusive situation," Mayo's mother, Ashley Pucheu, said.

Hammond Police Department is not investigating the incident. The Tangipahoa Parish Sheriff's Office is the investigating agency, but Pucheu says she would like to see a different agency, like Louisiana State Police, investigating the case.

"I don't trust them to investigate it properly, and because of who the perpetrator's son is, they are not going to do anything. They're just going to blow smoke up my butt and act like they're going to do something, but they're not, and I'm not going to stop talking until my daughter gets justice," Pucheu said.

We reached out to the sheriff's office for comment. A spokesperson sent a quote.

"As with any investigation, if additional assistance is needed, we will not hesitate to ask for it, no matter the level necessary."

Following Officer Bergeron's arrest, his father, Hammond Police Chief Edwin Bergeron Jr., released a statement.

"As Chief of Police, I want to assure the public that all normal policies, procedures, and protocols have and will be followed regarding the investigation involving Officer Corey Bergeron. Because the Hammond Police Department is not the investigating agency in this matter, we will respect the investigative process and allow the appropriate agency to conduct its investigation.

As a father, I will say that I have personally watched multiple videos and read many text messages involving my son, Corey, and I believe those videos and messages raise serious questions about the truth of the allegations made against my son. Also, it is extremely difficult to watch your child go through a situation such as this.

At the same time, I recognize that this matter must be handled through the proper investigative and legal processes. I believe the facts will ultimately come to light and Corey will be exonerated of all charges."
