Early Life and Background
On September 13, 2008, a family used to bright lights and hectic sets welcomed Mekhai Allan Andersen. Actress A is his mother. J. Cook, recognized for playing Jennifer JJ Jareau on Criminal Minds. His father, Nathan Andersen, is creative and family-oriented off screen. The mix of on-camera and off-camera living defined Mekhai’s early years.
He watched TV as a toddler. The Criminal Minds toddler that played JJ’s son was easily found. Mekhai played Henry LaMontagne, a BAU background figure. He was one of those rare young performers who enters a scene through the plot and makes it feel like home.
He has developed with a calibrated public presence. Fans know him from his name and screen legacy, yet he lives an ordinary teen life. With acting credits come sports, school, and family accomplishments. It is lived partly in studio light and partly in sunshine.
Family Spotlight
Mekhai’s family story begins with his parents and extends into a tight sibling bond.
- A. J. Cook, mother, is a Canadian born actress who has anchored Criminal Minds for many seasons as JJ. Her professional consistency gave Mekhai a front row seat to television production from an early age.
- Nathan Andersen, father, appears in family features and red carpet galleries as a steady presence. While not an actor, he has shared in the creative environment around the series and its community, often seen supporting his wife and sons at events.
- Phoenix Sky Andersen, younger brother, was born on July 23, 2015. Like his big brother, Phoenix has appeared on Criminal Minds in a child role. The brothers’ cameos link the family’s real life to the fictional family of JJ and Will LaMontagne.
The family’s roots stretch from Canada to the United States, a North American arc that mirrors A. J. Cook’s career path and the show’s Los Angeles based production. The result is a family tree with branches in two countries and routine travel shaped by filming schedules and premieres.
On Screen as Henry LaMontagne
Multiple Criminal Minds seasons have the modest but beloved Henry LaMontagne part. Henry’s Christmas, birthday, and family sequences humanize JJ’s life outside the BAU. Those scenes made Mekhai a show staple.
Key aspects of his on screen presence:
- Debut as JJ’s son during the show’s late 2000s seasons
- Recurring appearances as the character aged, including family centric scenes
- Participation in the revival era listings that kept the LaMontagne family visible to viewers
Many fans identify with Henry. He reminds the BAU that its job costs but yields a safe house. Mekhai’s development lends a subtle sense of time to the tale. The camera captures him in moments, a few sentences, a quick hug, and JJ’s family tale continues.
