Maybe something like this would be of use...
def sentence_locator(s, sub):
cnt = s.upper().count(sub.upper())
if not cnt:
return None
tmp = []
idx = -1
while cnt:
idx = s.upper().find(sub.upper(), (idx+1))
a = -1
while True:
b = s.find('.', (a+1), idx)
if b == -1:
b = s.find('.', idx)
if b == -1:
tmp.append(s[a+1:])
break
tmp.append(s[a+1:b+1])
break
a = b
cnt -= 1
return tmp
