GREENWICH - Police say they have arrested four men behind two armed robberies and shootings in southwestern Connecticut.

According to investigators, two of the men held up the Shell gas station on West Avenue in Norwalk in October 2009. They say the attendant, Jose Joaquin Morales, 33, was ordered to open the register and lie on the ground before he was fatally shot in the head.

Officials say one of the suspects also shot a 37-year-old clerk during a holdup at a Mobil on the Run in Greenwich that November. That attendant barely survived.

Police say Alain Leconte, 22, formerly of Stamford, has been charged in connection with both crimes. Mustafa Jacobs, 24, formerly of Stamford, is also being charged in connection with the Norwalk murder.

Investigators say Taran Nelson, 23, of Waterbury and David Wash, 37, of Bridgeport, face charges in connection with the Greenwich shooting. Leconte and Jacobs are currently in jail on unrelated charges.
