imperfect and tratar
Was reading an article today and was a bit confused by these two sentences any help would be great
- en 1985, el agente de la DEA Enrique Camarena había sido asesinado en Guadalajara
- my question is why is the imperfect haber being used when the year is given, it is because its background information for the rest of the paragraph?
- no tardaron en pelearse con otros integrantes de la organizacion
- how is the verb tardar being used here
Thank you
