Police: Louisiana man shoots 4 family members, then himself

Dennis Carter Sr., 50, also shot and critically injured his pregnant daughter-in-law, the parish sheriff's office said in a statement. The shootings occurred Saturday night in the town of Holden, Louisiana.

Authorities were dispatched to a report of shots fired at a home about 10:40 p.m. Upon arrival, they found three people dead and the fourth -- Amber Carter, 25 -- in critical condition, the statement said.

Those killed were Dennis Carter Jr., 26, Amber Carter's husband; their son Mason Carter, 2; and 49-year-old Donna Carter, mother of Dennis Carter Jr. and estranged wife of Dennis Carter Sr., police said. All had been shot to death. A 16-month-old child at the home was unharmed, authorities said.

Deputies believe Amber Carter attempted to escape from the gunman by jumping from a second-story window, holding Mason in her arms, the statement said, but the boy did not survive his gunshot wounds.

(...) Amber Carter was flown to a Baton Rouge, Louisiana, hospital, and later transferred to New Orleans, Rushing said. She was in critical condition as of Sunday morning.
