TWO bloody handprints were found on the truck of the dad who is on the run after he allegedly killed his three daughters.

The Decker sisters who were allegedly murdered by their dad, Travis Decker, likely died of asphyxiation.

Paityn, 9, Evelyn, 8, and Olivia, 5, were found dead at a campground in Washington state on Monday after their mom reported them missing on Friday.

Cops are still searching for Decker, 32, who is accused of killing his daughters during a planned custody visit on Friday.

Near where the girls’ bodies were found, cops located Decker’s white 2017 GMC Sierra truck, which he was reportedly living out of at the time of the gruesome crime.

His car was found abandoned with two bloody handprints, police records show.

It’s unclear who left the handprints.

Personal items like blankets, food, and a wallet were left on the center console of the truck.

Cops said the campsite showed signs of being recently used as a tent was set up with a cooler.

The girls’ bodies were found at around 5 pm on Monday near the Rock Island Campground in Wenatchee, which is about three hours east of Seattle.
