Night of the Juggler (1980)

A tough cop goes on a citywide rampage when his daughter is mistakenly kidnapped by a psycho. The psycho had originally targeted someone else's daughter, but is just as prepared to kill anybody unless his colossal ransom demands are met.

There is no juggling other than in the title, which comes from the nickname the police give to the killer, which is a bad pun on the fact that he cuts his victims' jugular veins.
