Virginia ? The victims of a gunman’s violent rampage in central Virginia included the suspect’s sister and brother-in-law, as well as two other adults, three teenagers and a 4-year-old boy, according to authorities who charged the alleged shooter with first-degree murder on Wednesday.

Christopher Bryan Speight, a 39-year-old security guard, surrendered to police at daybreak after leading investigators on an 18-hour manhunt following the slayings at a house in rural central Virginia where deputies found a mortally wounded man and seven bodies.

A bomb squad discovered a multitude of explosives at Speight’s home, and crews were detonating the devices into the night.
