Cause of Death for Jack and Kristina Wagner's Son Harrison Requires 'More Investigation': Medical Examiner

The spokesperson for the L.A. Coroner's Office is still investigating the details surrounding the death of Jack and Kristina Wagner's son, Harrison Wagner.

"Cause of death is deferred," the spokesperson tells PEOPLE. "Deferred means that after an autopsy, a cause of death has not been determined and the medical examiner is requesting more investigation into the death, including additional studies."

"Once the tests/studies come back, the doctor evaluates the case again and makes the cause of death determination," the statement concludes.

Meanwhile the 59-year-old actress, who currently appears on General Hospital as Felicia Scorpio, also reflected on spending time with her two sons at the Wagner family ranch.

"A bittersweet farewell to the place we called Wagner Ranch for 25 years," she wrote on May 20 beside a photo of the trio on the property. "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."

Kristina continued, "Oh Ranch, it's time to part. We'll miss you so much with our heartwarming memories. We know that there are many opportunities for joy ahead. #grateful #PeterandHarrison #lovemysons."
