In audio of an August 23 phone call acquired by TMZ Sports, a person speaking with his ex-girlfriend says, "I'm gonna ask you this one more time before I take it to another level. Can I have my son here, please?"
When the woman says no, the other person responds, "I'm gonna make sure I put a bullet in your f--king head."
The woman said the voice in the recording belongs to Cousins, and she submitted the audio to the Mobile Police Department in Mobile, Alabama.
She has reportedly filed a restraining order for her and her son against Cousins, although she said she is open to Cousins having supervised visits with the child.
In addition to the audio recording, West said Cousins told her he would kill her "even if he didn't have to get his hands dirty doing it."
She has also said in court documents that Cousins once choked her.
"We are aware of the allegation involving DeMarcus Cousins and, of course, take this claim seriously," the Lakers said in a statement to Ohm Youngmisuk of ESPN. "We are in the process of gathering information and will reserve further comment at this time."
After spending the 2018-19 season with the Golden State Warriors, Cousins signed a one-year, $3.5 million contract with the Lakers this offseason. The 29-year-old veteran is expected to miss the entire 2019-20 campaign, though, after tearing his ACL during a workout.
