A series of police raids throughout Los Angeles this week swept up suspected MS-13 street gang members who police said were tied to the fatal shooting of a homeless man in a Valley Glen park in January.

Los Angeles Police Department officers descended on residences across the city early Wednesday, serving search warrants on 10 locations, arresting five people and seizing “a myriad of weapons, ammunition, electronic media and gang paraphernalia,” according to a written statement.

Most of the operation occurred in the San Fernando Valley, where raids were conducted in Panorama City, Van Nuys, North Hollywood and Reseda. But police also went to homes in San Pedro in the city’s harbor area, and Huntington Park in L.A. County.

Most of those taken into custody were arrested on probation violations — none apparently participated in the killing itself. But police believe all of those taken into custody were “in possession of evidence” linking the gang to the Jan. 14 killing of 34-year-old Bradley Hanaway at Valley Plaza Sports Complex, as well as several assaults at the park in the weeks after, said Detective Marco Evans.

“We know that they are connected with the actual homicide in January,” Evans said. “And we also know that the particular clique of MS-13 in the Valley were involved in the aftermath of the homicide.”

The raids follow the arrests of three men in January and February who police said were involved in Hanaway’s murder. Luis Gonzalez, 19, and Edwin Martinez, 21, were both arrested by L.A. County sheriff’s deputies from the department’s station in Calabasas on Jan. 28, according to booking records.

Gonzales was charged with one count of murder, with the special allegation that he committed the killing in the furtherance of activities of a criminal street gang, according to the district attorney’s office. Martinez was charged with one count of being an accessory after the fact. And both were charged with one count each of criminal street gang conspiracy.

It’s not clear who the third man arrested in February was. A district attorney’s office spokesman was not aware of another case associated with the murder.

A city employee discovered Hanaway’s body near the bathrooms at the park at around 9:30 a.m. on Jan. 14, police said at the time. The employee saw the man lying face down on the ground, then turned him over to see that he had been bleeding, said Detective Dave Peteque.

Police said Hanaway was killed about eight hours before. He was asleep on the ground at around 1 a.m. when multiple men approached him. Detectives said the men “accosted” him, then shot him to death.

Details about the motive for the killing were not immediately released, but Evans said police now were sure that the man was targeted for his gang ties. He said Hanaway was a documented gang member, and was homeless by the time the suspects found him at the park.

According to the coroner’s office, Hanaway died from multiple gunshot wounds.

About a month after the killing, police said five assaults on homeless people were reported at the park. All of the violence was part of the MS-13 gang members’ attempts to “establish a foothold by directly challenging rival gangs in the area,” officials said in the statement.

“We see acts of violence like this are normally utilized by streets gangs to instill fear and intimidation in the community,” said Evans.

Police this year have been cracking down on gangs still active in the San Fernando Valley and beyond. In February, FBI agents and LAPD officers arrested more than two dozen members of the Vineland Boys, a North Hollywood gang founded in the 1980s, amid a wider sweep of gang hangouts across the city.

Investigators were still tracking down several additional suspects Thursday, Evans said. All were believed to still be in Los Angeles. In the statement, police said “we expect to have them in custody in the coming days, and do not believe there is an immediate threat to the community.”

During the raids, police found 20 children, who were all assessed by the Department of Children and Family Services. No children were removed from the homes, but DCFS is pursuing three investigations of nine children, according to the statement.
