CENTRAL ISLIP - Officials say more detailed testimony is expected today in the trial of two MS-13 gang members.

Heriberto Martinez and Carlos Ortega are accused in a string of execution-style killings.

Yesterday, a former gang member testified that Martinez was involved in the murder of an "El Rancho Bar" bouncer in Hempstead in 2010.

The former gang member also testified that Ortega is linked to the murder of another MS-13 member who refused to kill rival gang members, according to Newsday.

The witness will return to the stand today.
