Wennell - Bracegirdle connection.

Further research on the murder of Adeline Bracegirdle in 1968 has brought up another person of interest - a male with surname of Wendell who in 1968 was living in Tottenham. Hearsay evidence states that by c 1984 he was "locked up for murder" and was either in or had been in Parkhurst. I have done google searches, newspaper searches on Find My Past etc. but haven't come up with any info.

Does anyone have any info of a murder or other serious offence committed by a man named Wendell? or any ideas where I could try next?

Thanks
Victoria
