Investigators are asking for the public’s help in what they called a “heinous” and “sad” crime.

Dayton police Lt. Gregg Gaby on Tuesday wouldn’t answer specific questions about how many shots were fired and what caliber of bullet killed Sherrell Wheatley as she was walking home after feeding a neighbor’s dogs.

"We really have nothing other than at this point the suspect vehicle is possibly a silver-colored (Ford) Taurus or possible (Chevrolet) Impala-type vehicle. We're not sure of the exact make and model of the vehicle," said Gaby, commander of the violent crimes bureau.

“What we are asking is anyone in the neighborhood that saw any of this or has any information on this, please contact the Dayton Police Department.”

“At this point, we do not think that they intentionally targeted her, but we don’t know that,” said Gaby, who added that nothing in the investigation has revealed why Wheatley was targeted.

Gaby said witnesses heard gunshots and saw the vehicle, but nothing has tied the suspect vehicle to other crimes. Gaby also said a September 2017 shooting at the same residence does not yet tie in.

"This is the type of crime that hopefully the community will be incensed by and come forward and help out with and say, 'Hey, I've got information on it,'" he said
