Almost five weeks after the murder of eight-year-old Jonah Hwang, Pomona police chief Paul Capraro confirmed that an arrest has been made in connection to the case.

In a press conference Monday, Capraro announced that suspect Sengchau Houl had been arrested Sunday. According to the Los Angeles Times, Houl had cooperated with police at the time of arrest and a firearm had been discovered in Houl’s car. Houl has no prior gang affiliations or criminal history, but his car has been tied to other shootings at the same location where Hwang was shot, the police chief reported.

Capraro described the investigation as an around the clock effort, incorporating efforts from the Federal Bureau of Investigation and other Los Angeles county law enforcement agencies, according to the Daily Bulletin.

“Nobody rested in this station until we got at least to this point,” Capraro said at the press conference. “I want the community to know that the members of this Pomona Police Department poured their hearts and souls into solving this crime. We’re a long way from getting to the end of things. We’re going to see this through.”

Jonah, the son of Diamond Bar High School science teacher Johnny Hwang, was the victim of a drive-by shooting on Feb. 10 while visiting the home. The house had previously been targeted by a shooter, and in the interval between Jonah’s death and the arrest, the house was again damaged by gunfire.

The case was expected to be presented to prosecutors on March 28.
