Motive sought in fatal shooting of 8 children in Louisiana as police give timeline of massacre

As an investigation continued into the motive of Sunday's fatal shootings of eight children in Shreveport, Louisiana, allegedly by the father of seven of the victims, police officials released a timeline detailing the 68-minute massacre.

"April 19 ... will be written in the pages of history as one of the worst days that could have ever happened here in Shreveport," Chief Wayne Smith of the Shreveport Police Department said at a news conference on Monday.

Smith said the suspect, Shamar Elkins, a former member of the Louisiana Army National Guard, allegedly used an assault-style pistol to kill seven of his children and an eighth child related to him. A teenage boy was also injured when he jumped off the roof of a house to escape the shooting, police said.

While Elkins died after police opened fire on him following a car chase, Smith said it remains unclear whether he was shot to death or died by suicide.

Smith said domestic violence is believed to be the primary motive behind the killings. The chief said two women, including the mother of seven of the children who were killed, were wounded in the incident and remain hospitalized.

He said investigators are probing five different crime scenes connected to the shootings.

Police said the children killed, siblings and one cousin, ranged in age from 3 to 11.
