This is by far my favorite book from the Abby Cooper, Psychic Eye series.

When Abby receives a mysterious voice mail from her sometimes partner, Candice, her senses trigger alarm. Candice is wanted for the cold-blooded murder of a doctor and despite surveillance video showing her pull the trigger, Abby has a hard time reconciling that act with her best friend. When Abby decides to sneak away and help Candice, things get dicey and fast. Abby is going to need all her psychic abilities to keep herself out of danger and help Candice.
