Enea TAPELLA (aka 達碑立神父) [1929-1977]

I am currently working on a research project about an Italian Catholic priest, Father Enea Tapella (達碑立神父) from the (Pontifical Institute for Foreign Missions, PIME), who spent his good years in Hong Kong between 1957 and 1977, and was renowned with his unselfish contribution to mentally handicapped children in Hong Kong.  In those years not only support for this group of people, and their parents, were very limited, they were also subject to unfair discrimination by other people.  Father Tapella initiated volunteer groups in several parishes he served in Hong Kong to help and serve mentally disabled persons, and his works contribute to a strong foundation and birth of Fu Hong Society (扶康會), started in 1977 and right after his unfortunate death in a traffic accident at Repulse Bay.

There are a few things about his life in Hong Kong I would want get help from anyone who might have the following information:

1. Were there any documentaries, shot in 1950s to 1970s (or after), that talked about the generally poor condition and public's discrimination against disabled persons in HK in those years?  I was told that there's a RTHK programme documenting their poor condition, with one episode showing a kid got chained onto his bed, while his parents were out, inside their home in the resettlement area (徙置區).
2. One of the most interesting things about Father Tapella was that he would organize summer camps for disabled persons, at Tai Long Sai Wan (大浪西灣) and other remote beaches, with the help of the British Army.  The latter would carry volunteers and disabled children using landing crafts from their camps in Kai Tak / Choi Hung all the way to Sai Kung.  They could do these due to a community outreach programme supported by the Army HQ.  Would anyone know any details about that?
3. I was told Father Tapella had support from Elsie To during the 1960s.  However I didn't hear any works by Elsie To on disabled persons, apart from her social activities.  Are there any details available on this?
4. When Father Tapella was searching for a suitable camp site for disabled children, and unfortunately injured from a fatal accident in 1977, I was told that there was an announcement made in either RTHK or CRHK asking people to help donating blood to Father Tapella.  I wonder if this audio transcript is still available, or if I want to get one, where can I look for that?

If anyone has any information on the above, or even amazingly do know stories (or had encounters!) with Father Tapella, please do let me know and contact me, either posting information here or send me e-mail at kuievita@gmail.com.  I would be much appreciated for any kind replies.
