JACKSON, MISS. Officials have not yet said who is responsible for the shot that killed a 3-month-old baby when his father died in a shootout with police on a highway last week in Mississippi. Activists with Black Lives Matter Mississippi are calling for the release of police body camera footage of what happened May 3 near Biloxi. Investigators won t say whether any officers were wearing body cameras at the time. A group gathered Sunday by Interstate 10, near the site of the shooting, to pay tribute to the life of infant La Mello Parker and two people who were killed earlier May 3. Authorities said Christin Parker, 32, and her nephew Brandon Parker, 26, were killed by La Mello s father, Eric Derrell Smith, in a domestic dispute, leading to the police chase and standoff in which Smith and the baby were killed.
