McCants’ father told police his son said he wanted to show him a rattlesnake he had found, Austin’s Fox 7 reported, citing an arrest affidavit.

The father got in the car with McCants, who drove about a half a mile from his father’s home, according to the station.

The father told police his son lured him to an area near the edge of the cliff where the rattlesnake supposedly was.

As the father looked for the rattlesnake, McCants allegedly shoved him off the cliff, sending him tumbling into dense brush and undergrowth, Fox 7 reported.
