Because there's no indirect object in your sentence.

Elmo se escapó del tiro: first option he wasn,t hurt; second optión he didn,t go to his appointment with the shot. Both option refer the same verb: "escaparse" it is reflexive verb: i do the action, I benefit from the action (like "lavarse": se lava las manos-- he does the action he benefits from the action) Me escapé de la cárcel; TE escapaste del examen; SE escapó de casa; NOS escapamos todos los fines de semana a la montaña; ¿OS escapáis esta noche conmigo?; Los perros SE escaparon por ese agujero. But if i say "le lavo los dientes a mi perro" i do the action but i don,t get benefit from the action. is my dog ​​who gets white teeth. "Elmo se escapó del tiro" has no a third part to benefit from his action. we don,t need LE... p, ej. ME digo: "no lo hagas" (i say to myself) LE digo: "no lo hagas" (I tell a third person not to do something)

That is exactly what I wanted to say. A Elmo se le escapó un tiro. I was asking a friend how to use acciones involuntaries and he wrote this for me leaving out the indirect object. It was not until I clarified it with the Spanish maestra that I understood it clearly. Thank you. Gracias.

Im not sure what do you want to say with that. If you want to say that Elmo fired his gun accidentaly, you can say: "A Elmo se le escapó un tiro" If you want to say that Elmo dodged the bullet, then you can say: "Elmo esquivó la bala" Thats in my opinion. I hope others can correct me if i am wrong. :)
