In the early hours of May 1, 2015, Joselo Jose Campusano, 21, was killed inside the restroom at Bali’s nightclub on Essex Street in Lawrence, Massachusetts. Police were called just before 1 a.m. for a fight and found Campusano suffering multiple gunshot wounds; he died at the scene. Family members remembered him as a friendly man and a devoted father who preferred to spend time at home with his young daughter.

Investigators say a man followed Campusano into the restroom, shot him, then fled. The suspect was initially identified as William Perez but was later linked to the alias Yssael Lantigua-Alecon, age 34, of Methuen, who reportedly uses multiple fraudulent identities. An arrest warrant charging murder and related firearms offenses was issued, and authorities say the suspect fled in his sister’s SUV and has not been captured; he was placed on the state’s Most Wanted list and is considered armed and dangerous.

Anyone with information about Joselo Campusano, the shooting at Bali’s nightclub, or the whereabouts of Yssael Lantigua-Alecon is asked to come forward.
