While on a hunting trip in the Forest of Lognes, near Livry, in Picardy, Bilichild, along with her husband and her eldest son, the five-year-old Dagobert, were assassinated by a band of dissatisfied Neustrians—Bodilo, Amalbert and Ingobert.
He was buried in Saint-Germain-des-Prés, near Paris, where the tombs of him, Bilichild, and his infant son Dagobert were discovered in 1645; the contents were pilfered.
