Anthony Santiesteban, 30, of Centereach, was arrested Tuesday and charged with second-degree murder in connection to the death of 33-year-old East Patchogue resident Martina Thompson, according to the Suffolk County Police Department.

Thompson was shot and killed in Coram in the rear parking lot at 24 Middle Country Road around 1:25 a.m. on Saturday, Oct. 29, police said.
