Angela Kukawski had been reported missing from Sherman Oaks on Dec. 22, according to police.
She was later found dead inside her vehicle in the 1500 block of Patricia Ave in Simi Valley.
“Angela was truly the best. She cared about every one of us and made things happen that were impossible,” the Kardashian-Jenner family said in a statement to CNN. “She will be greatly missed and we send our sincere condolences to her family and loved ones during this most difficult time.”
Authorities have arrested Kukawski’s 49-year-old boyfriend, Jason Barker, on suspicion of murder.
Detectives allege that Barker killed Kukawski inside their Sherman Oaks home, placed her inside her vehicle before driving her body to Simi Valley and leaving the car there.
He was booked into Van Nuys Jail and the Los Angeles County District Attorney’s Office filed murder charges against him.
Barker is next scheduled to appear in court on Jan. 12.
It is not yet known if Barker has retained attorney.
On Wednesday, Minaj took to her Instagram stories to post a tribute to Kukawski.
“Hardest working, most reliable, sweetest person you could ever know,” Minaj wrote. “You didn’t deserve this Angela. My heart is breaking for your children. Rest in Peace.”
Offset also posted on his IG stories.
“R.I.P Angie such a sweetheart you helped me so much,” he wrote. “Talked to you every week I’m in disbelieve (sic) SMH prayer to your soul.”
