Santo Domingo , Dominican Republic ( CNN ) -- Baltimore Orioles pitcher Alfredo Simon said Monday the shooting death of a 25-year-old man over the weekend was an accident . `` In truth that young man was my friend , like a brother , '' he said of Michael Esteban Castillo . `` It was n't a thing like we began arguing and I started shooting . It was some accident ; it happened by accident , '' Simon said , speaking at the police station where he turned himself in . `` That 's why I came here -- to open my soul , '' he said . Simon surrendered to Dominican National Police early Monday morning to face murder charges . Simon is also accused of wounding Castillo 's 17-year-old brother , Starlin . The injuries to the brother are not life-threatening , police said . Simon 's attorney said the major league baseball player had fired his gun into the air . Puerto Plata District Attorney Victor Mieses said Monday that he will seek three months of incarceration against Simon and widen the investigation . Puerto Plata Assistant District Attorney Juan Carlos Hernandez , who is handling the case , said of Simon , `` So far he 's the one . There 's no doubt about the incident . '' Hernandez added that it 's `` normal '' to seek temporary incarceration when there 's a shooting death . Police spokesman Maximo Baez said Simon turned in his gun as part of the investigation into the shooting in the Los Salados section of the town of Luperon , in the province of Puerto Plata , early Saturday . Simon was accompanied by his attorney , Carlos Olivares , and by fellow Oriole Julio Lugo , Baez said . `` The projectile 's trajectory was only up into the air , so much so that he left , '' Olivares said of his client . `` He understood that nothing had happened at the moment . And 45 minutes later , when he was eating at a some restaurant or discotheque , somebody tells him , 'Hey , you 're the one who killed so-and-so . ' '' Lugo said , `` We 're concerned about his career or whether he 's going to have to go to jail . We do n't know if it was him . He wants to clear up what happened , but no one really knows if it was him for sure . '' Simon was scheduled to appear at the courthouse in Puerto Plata for arraignment Monday , Baez said . Simon , 29 , hails from Santiago . He joined the Orioles in 2008 . The Baltimore Orioles declined comment . Journalists Jorge Pineda and Diulka Perez contributed to this report .
