During the investigation, a multitude of suspects were detained, and although one reportedly confessed to the crimes, no one was ever convicted of the murders, and the identity of the killer remains a mystery.

[4] On August 18, 1960, 51-year-old Mrs. Modie Hall and her 10-year-old granddaughter, Mary Foster, were brutally attacked in their home on the 69th block of San Pedro and Avalon by a man wielding a blunt object.

Hall’s son-in-law, 30-year-old Floyd Harris, was awakened by moaning and the distinct sound of a rubber ball bouncing on the floor.

The attacker was believed to be the elusive “Bouncing Ball Killer”, who remained at large, but despite efforts, police were unable to apprehend the suspect.

[6] The murders were quickly grouped together, and based on Adela Williams' description, a composite sketch of the suspect was made and released by police artist Ector Garcia in June 1960.

[9][10] By the end of June, over one hundred tips had been submitted to local law enforcement from citizens who claimed to have information in the case, but none led to any arrests.

While being booked, police noticed similarities in Malveaux's facial features to that of the composite sketch of the Bouncing Ball Killer.

During his interrogation, Malveaux told police that all of his friends also thought he looked like the killer but said that rumors of it being him was "a lot of boloney".

He had a criminal record and at the time of Thoeren's murder, Clemmons was on parole after serving two years at San Quentin State Prison for a hit-and-run in 1956.

[16] On September 6, 1960, police arrested 28-year-old Henry Adolph Busch for the attempted murder of a co-worker in Los Angeles.

On August 28, 1961, Long Beach police arrested 20-year-old Charles James Golston on charges of murder in the rape and strangling of 81-year-old Dora Ann Cutting.

[20] Los Angeles police were made aware of the arrest and sought to question Golston in the Bouncing Ball murders.

[22] In April 1963 Golston and three other death row inmates, Don Franklin, John Vlahovich, and Joseph Rosoto, were scheduled to be executed on May 3 of that year.
