A woman and her infant son were found dead on the side of an interstate on-ramp in North Little Rock, Arkansas, Tuesday morning, and police say they are investigating the case as a homicide.

Teangela Tate, 27, and her 2-month-old son Noel Mott were found dead beside the Interstate 440 ramp from Highway 165, KARK reported. A toddler, 1 1/2 years old, was hospitalized in critical condition. Tate was also the mother of that child.

Police provided little information about the investigation. They initially called it a death investigation but later said evidence led them to escalate it to homicide.

They said an autopsy for Tate and the infant would provide information about cause of death.

Anyone with information is asked to call the NLRPD tip line at 501-680-8439 or Detective Gibbons at 501-771-7149. These tips can remain anonymous.
