Peter Wagner has broken broken his silence for the first time since his younger brother Harrison passed away earlier this week.

Harrison, the son of beloved “General Hospital” actors Jack and Kristina Wagner, was found in his car early on Monday morning in a North Hollywood parking lot. He was only 27.

On Wednesday, Peter, 31, posted a series of photos of his brother on Instagram, captioning his post, “Always with you.” Some of the photos showed the two of them together as children. They each featured prominently on each other’s social media up until Harrison’s passing.

Neither of Harrison’s parents, Jack, 64, nor Kristina, 59, have publicly commented on their son’s death.

The executive producer of “General Hospital”, Frank Valentini, also spoke out on Wednesday, sending condolences to the actors from everyone who works on the famous soap. “On behalf of myself and the entire #GH family, our hearts go out to Kristina Wagner, Jack, and their family during this devastating time,” Valentini tweeted. “We ask that you respect their privacy and keep them in your thoughts.”

Though Jack and Kristina divorced in 2006 after 13 years of marriage, the actors remained friends and continued to co-parent.

Harrison is also survived by his sister, Kerry, whom Jack has from a relationship prior to his marriage to Kristina.

According to a report from the Los Angeles Medical Examiner’s Office, Harrison’s cause of death has not been released and an autopsy is still pending, as ET and other outlets have reported.

In addition to “General Hospital”, Jack has starred on “Melrose Place”, “The Bold and the Beautiful”, and “When Calls The Heart.” Kristina still appears on “GH” and also appeared alongside Jack on “When Calls The Heart” from 2015 to 2016.

Jack has been open in the past about his son’s struggles with addiction, though it’s not at all clear whether Harrison’s past problems with substance abuse played a role in his passing. In July 2016, Jack tweeted that Harrison had gone missing for 5 days after suffering a relapse.

“I fear for my youngest sons safety [sic],” the actor tweeted. “Harrison has struggled w drugs & alcohol just as I did when I was younger. He’s relapsed & is MIA 5days [sic].”

Harrison last posted on Instagram on May 22. “Focus,” he captioned a photo of himself. “YOU are left with YOU and your thoughts.”

Harrison was often to be spotted with his family on both his father and mother’s Instagram pages. His mom Kristina’s post was with Harrison and his brother Peter. Take on the porch of their family ranch which they had just sold, Kristina wrote, “A bittersweet farewell to the place we called Wagner Ranch for 25 years. The prickly beauty of the high desert and a landscape surrounded by national forests always reminded us that there is peace when you are willing to look for it.” She added the hashtags, “#PeterandHarrison” and “#lovemysons.”
