Nick Reiner, who didn't enter a plea Wednesday, faces murder charges after, authorities say, he killed his parents at their Los Angeles home over the weekend.

One of the newly released videos appears to show Nick Reiner, 32, moments before his Dec. 14 arrest near the University of Southern California. In the video, he's wearing jeans, a striped jacket and a baseball cap. He's seen with a red backpack slung over one shoulder as he enters a gas station and purchases a drink.

Rob Reiner's son Nick Reiner was "entitled" and "wanted to live a life that didn't exist," a source close to the family tells PEOPLE. The 32-year-old, now charged with killing his parents, previously spoke about having "no identity" and "no passions" growing up in the shadow of a famous father.

Video of the 32-year-old apprehension has emerged as the adult son of the Hollywood icon booked on suspicion of murder on Sunday was being held without bail.

Rob Reiner's friend Barry Markowitz said the filmmaker's son Nick Reiner appeared to be doing well during a recent stay.

Alan Horn, who is a longtime friend of Rob Reiner for over 50 years and co-founded Castle Rock Entertainment with Reiner, talks to CNN’s Erin Burnett about the murder of the longtime Hollywood director.
