There is an additional unknown child of middle school age who may be part of the Akai family.

Speculation

Unknown child

Some fans think the mysterious child who looks like a member of the Akai family might be Mrs. Akai after being shrunken by APTX 4869.

Unknown (2nd son)

Assuming the middle brother is between 16 (assumed lower range for Masumi's real age) and 35 (assumed upper range for Akai's age based on his appearance and reasonable full-blooding sibling age separation) the following characters could qualify as suspects in reverse order of their introduction date. It's possible the middle brother is a minor character who was a suspect or witness in a case, but did not distinguish himself or demonstrate his intelligence. It's also possible for the middle brother to be a character who has not been introduced yet, but will be later in a flashback. Some fans think the mysterious Unknown child who looks like a member of the Akai family might be the brother after being shrunken by APTX 4869.
