On Saturday, first responders discovered Perry's body after receiving a call to his residence, though they did not initially reveal his identity. While Perry had been open in the past about his struggles with substance abuse, PEOPLE reports that no drugs were found at the scene, and police do not suspect foul play.

Fire Department confirmed to PEOPLE that first responders arrived at the house at approximately 4:07 p.m. on Saturday "An adult male patient was deceased prior to first response arrival," an LAFD spokesperson told the outlet. "The patient was found by a bystander who had repositioned the victim where the head was out of water" in a freestanding hot tub. "Firefighters pulled the victim out of the jacuzzi and did a quick medical assessment to find he was deceased."

He also appeared in a number of other TV shows — such as Ally McBeal, The West Wing, and a remake of the Odd Couple — as well as beloved comedy films like Fools Rush In and 17 Again.

After his death, Perry's former assistant, Briana Brancato, issued an emotional tribute to the late actor, writing in an Instagram post, "I've expressed my deepest gratitude to him on numerous occasions, not only for guiding me into a career I cherish but also for allowing me to take care of him for 7 years." She continued, "Along [with] the countless other experiences I'm thankful for. From witnessing him in his genius to sharing in his worldly adventures living around the world, he took me on a remarkable journey."

Alongside photos of Perry, Brancato wrote that her "heart is heavy" but added that she believes "celebrating my memories is the most profound way to honor his legacy." Brancato concluded, "I hope that up there, in the great beyond, Mattman is sending us signs. We truly need them. You'll forever be in my heart. I love you Matty."
