A 43-year-old Mililani man charged with two counts of second-degree attempted murder in the shooting of two men in a Mililani Park early Monday morning appeared in District Court this morning.

Richard P. Silva, who is being held on $500,000 bail, appeared before District Court Judge Barbara Richardson, who set his preliminary hearing for 1:30 p.m. Friday.

Police said the shooting was apparently the result of an argument between acquaintances that started at the Shack restaurant in Mililani Sunday night.

Silva allegedly challenged two men to a fight at the park. Neighbors heard about five or six shots at about 1:30 a.m.

A 38-year-old man went to the hospital in very serious condition and a 41-year-old man was hospitalized in serious condition.

Silva turned himself in at the Wahiawa police substation at about 4 a.m. Monday after the shooting.

Silva has five previous convictions for misdemeanors or violations in Hawaii, including a felony conviction for assault in 1994, according to state records.
