Four killed in US murder-suicide

A US man shot his estranged wife, son and two-year-old grandson to death and critically wounded his pregnant daughter-in-law at their rural Louisiana home, then killed himself as police tried to pull over his car 20 minutes later, authorities said.

The shootings appeared to stem from an ongoing dispute between 50-year-old Dennis Carter Sr and his wife, Donna Carter, who had a restraining order against him, said Livingston Parish Sheriff’s Office Chief of Operations Perry Rushing.
