Crime Scene Investigation - Fans clash after soccer match

At a mass celebration after a soccer match, stones were fired at celebrating fans from catapults by fans of the losing team. During the following chaos, police arrested a fan who was holding a catapult. He claimed that someone passed him the catapult but he did not use it at all. He was arrested 40 m from where the injured fans lay.

A 10 m high fence separated the opposing fans. The suspect was 15 m away from the fence. The injured fans were on the other side of the fence and 25 m away from it. Eyewitnesses testified that the stones were shot from a height of 1.5 m, at an angle of 65° with an initial velocity estimated at 15 m/s.

One of the CSI investigators took a look at the data above and concluded, after some initial calculations, that the suspect was not telling the truth. He said that based on the height reached by the stone, it was possible that the suspect could be guilty.

Another investigator disputed this and said that, based on his experience, it was not possible for the catapult to shoot the stones so far.
(Gravitational acceleration = 10 m/s²)

(a) As the rookie in the CSI team, you are required to prepare a report on your own findings as to whether the suspect could/could not have injured the fans of the opposing team.
