I heard about this (was in Sosua last week) at the airport.
- Thursday evening at bank ATM beside SuperSuper.
- attempted mugging (ATM at bank); 2 landrones.
- undercover police shot first one dead (head) at bank.
- second one fled and was shot (body, legs) near Alligria (sp?) Bar.
- tossed in back of pick up and taken away; expired before hospital reached.
I saw nothing but was told and am only stating it now as it lends support to the OP.
