a North Plympton factory that had previously belonged to one possible suspect in the case, Harry Phipps (see below). Further excavation at a slightly different location on the site was undertaken in February of 2018, but nothing relevant was found. The excavations were based on two men reporting that as boys they had been paid to dig a hole in that area at around that time, and also based on geophysical testing which had identified anomalous disturbed soil. Animal bones were found, but nothing was found in relation to the Beaumont children. Possible suspects Bevan Spencer von Einem Bevan Spencer von Einem (born 1946) was sentenced to life imprisonment in 1984 for murdering 15-year-old Richard Kelvin, son of Adelaide newsreader Rob Kelvin.

While von Einem was known to have frequented Glenelg Beach to "perv" on the changing rooms, and was described as preoccupied with children, what argues against his involvement in the
