What do we believe happened?

Early morning a group of 3 jumpers went up Grotto mountain, Canada. Grotto is a 3600 ft Mountain, with 150 meters down to to a 50 meter ledge, that jumpers need to clear. The location has been jumped countless times without incident by local jumpers. Jumper struggled a bit, turning the 3-hour hike into a 5-hour trip up.
He was made aware of the technical details and difficulty of the jump on multiple occasions, but felt confident in his motivation/choice to jump. He had a good amount of experience on the wingsuit model he jumped. The previous day Jumper made an uneventful base jump with a controlled and smooth exit at a different location using the same gear, which boosted confidence in his ability. Arriving at the exit point, clouds didn't allow for clear visibility, so the jumpers waited around 4 hours for conditions to improve then
Visibility improved, with clear view from exit till landing, with a tailwind over the mountain creating a slight downdraft.
Jumper 1 was comfortable jumping, and started getting ready. Jumper also decided to jump, exclaiming "I'd rather jump than hike down." due to being tired. Jumper 3 decided to go back down, not being comfortable with conditions combined with a new wing suit.
Jumper 1, flying the same wing suit model, had an uneventful exit and flight, clearing the ledge nice and high. Jumper jumped second, and exited with a normal push, but 45 degrees head high. Instead of a normal start he started falling down upright/knee first.
He was observed by jumper 3, not moving forward but going flat, creating a very steep recovery arc.
He started flying too low, and impacted the ledge with his chest. He then tumbled down the mountain, coming to a stop on a ledge another 500ft lower. The severity of the impact shows death was instantaneous.
