The mother of Cathriona White, Jim Carrey‘s late girlfriend, has filed a lawsuit against the actor, blaming him for the makeup artist’s 2015 suicide and claiming that he gave her several STDs while allegedly concealing his diagnosis.

According to court documents obtained by PEOPLE, Brigid Sweetman is seeking damages from Carrey in a wrongful death and violation of the drug dealer liability act lawsuit.

Sweetman alleges that Carrey gave White “three STDs without warning her (Herpes I and II and Clamidia), lying to her about it, ‘dumping’ her out of concern for saving his own carefully crafted public image, calling her a ‘whore’ and shaming her, and then using his high-priced Hollywood lawyers and ‘fixers’ to intimidate and threaten her in an effort to silence her.”

In response to the new lawsuit, Carrey’s lawyer Martin D. Singer said in a statement to PEOPLE, “It is understandable that a mother who has lost a daughter will look for someone to blame. But in directing her grief and rage at Jim Carrey and joining this ridiculous lawyer’s attempt to capitalize on Cathriona’s suicide, Mrs. Sweetman is heading down the same dark path as Cathriona’s green-card ‘husband,’ Mark Burton.”

This is the second wrongful death lawsuit against the actor: White’s estranged husband Mark Burton sued the actor last month. Both Burton and Sweetman are being represented by the same lawyer, Michael Avenatti.

Sweetman and Burton separately claim that Carrey obtained the drugs that killed White under the false name “Arthur King” and provided them to her, despite knowing she was prone to depression and had previously attempted suicide.

In response to Burton’s earlier suit, Carrey said in a statement obtained by PEOPLE, “I will not tolerate this heartless attempt to exploit me or the woman I loved. Cat’s troubles were born long before I met her and sadly her tragic end was beyond anyone’s control. I really hope that some day soon people will stop trying to profit from this and let her rest in peace.”

Carrey further said that the drugs were taken from him without his knowledge.

White was found dead in her Los Angeles home on Sept. 24, 2015, surrounded by four prescription medications — Ambien, Percocet, Propranolol and Zofran — not in her name. Burton’s filing noted that a coroner determined that White had overdosed on Ambien, Propranolol and Percocet.

A toxicology report noted that when police checked White’s phone, they found texts from Carrey asking if she “knew where his painkillers went from under his sink.”

In addition, White was found with a note addressed to Carrey, according to her autopsy report. The note read, among other things, “Please forgive me. I’m just not for this world.” The couple had broken up just a week prior after initially splitting in 2013, following White’s alleged STD diagnosis.

The new lawsuit from White’s mother includes screenshots of conversations allegedly between White and Carrey discussing her supposed STD diagnosis, as well as a handwritten note from her to the actor.

Sweetman is seeking — among others — general damages, economic damages, funeral and burial expenses, punitive damages and attorneys’ fees.

“Jim Carrey should be ashamed of what he did to my daughter. And he should be ashamed for how he has used his Hollywood attorneys to badmouth Cat’s husband Mark with the hope that nobody will hold him responsible for what he did,” Sweetman said in a statement. “As a family, we want the world to know the truth about who Jim Carrey really is.”

Added her attorney, Avenatti: “The lies from Jim Carrey and his handlers need to stop. Instead of attacking a grieving family in an effort to avoid responsibility, why don’t they just try telling the truth about how Carrey gave Cat the STDs and then gave her the illegal drugs? Unlike Hollywood handlers, lab results do not lie.”

Of the STD claims, Carrey’s attorney Singer previously released a statement.
