As a solicitor how would you deal with a depressed client with these issues

To keep things short, how would you handle a client who has no previous criminal history but will be charged with ss1 and 17 Theft Act 1968 (because they found a wallet and spent £70 that was inside the wallet because apparently they could not find any identification of the true owner inside the wallet and therefore could not return it) and also charged with s1 Fraud Act 2006 (because she eventually did find a credit card and decided to spent £300).

The 45 year old struggles with money and lives with her parents who are very poorly, she is that depressed that she is considering killing them and then commit suicide.How would you deal with such a client?Obviously one would have to alert the police, what else should be done?Thanks in advance
