ST. PAUL, Minn. – These are early clues that police uncovered in the slaying of four people whose bodies were found in a Mercedes SUV hidden in a rural Wisconsin cornfield two weekends ago:

> A cigarette butt found in the cornfield near the abandoned revealed the smoker’s DNA.

> Shell casings were found in the vehicle.

> Darren Osborne, who has been charged, told police he followed his stepson, Antoine Suggs, from St. Paul to Wisconsin in a second vehicle but didn’t see the bodies in the Mercedes. Suggs also has been charged.

> Osborne said he gave his stepson a ride back to St. Pail.

> A police dashcam in Menomonie, on the route from St. Paul, showed a Mercedes in a parking lot three hours before the abandoned vehicle was found. By the time the officer could check on the Mercedes, it had driven off.

> Police later found droplets of blood in the Menomomie parking lot.

> Police also found blood droplets at a gas station in Wheeler, near where the Mercedes was abandoned.

 > Surveillance video at the Wheeler gas station showed Suggs driving the Mercedes, and his step father driving a different SUV.
