I'm suspecting that my mom's neighbor might indeed be the one who scammed my mom. How do I find help on this, including finding an attorney?

Thank you very much for the suggestions you guys have given me concerning my mom; Very challenging situation I'm in. So in speaking through a family member who my mom has confided in as far as her personal affairs,I was finally able to speak to that family member and according to her,way back in 2014( if some of you remember that my mom was being scammed and I was traumatized to seeing how I could handle this,with multiple trips I made to her place with no resolution), she would describe this neighbor of my mom to a tea,the neighbor that always led a helping hand to my mom and helping her handle financial matters,use my moms home depot credit cards without her permission,appoint herself as her poa at the time and who knows what else this leech person was doing behind closed doors with her being my mom's poa. This neighbor,when my mom who supposedly was extorted by another entity and supposedly needed the cash by selling one of her condos(and I ask myself "wasnt my mom renting that other condo and making money from it thus generating income?") executed the sell of that condo(have the records) and being ,as a convenience,a notary public as well,processed the sale of the condo,not seeing if there was a title company involved in the transaction( didn't see a record of this). (Mind you,my mom didn't go to college or was savy in any legal issues and also I was working in another state to know what transpired) After the sale was done and then my mom deposited or that neighbor deposited the check for the sale of the condo to her bank account,Then came the transactions(got a hold of the records and saw them).After one day after the check deposit,withdrawls in increments of $4,000.00 each time, As days passed on,more withdrawls from my mom's account,$3500.00 cash withdrawls,4000.00 more the next day,$5000.00 sometimes and as time went by those transactions were ongoing till the balance was to almost zero!.Anothe aunt of mine sent me an email stating that they received a letter from my mom to let them know that she might not be living much longer and that she is being extorted but NEVER TO LET MY SON KNOW about this! Also another neighbor who I celled to see if she saw any irregular behavior in my mom,she asked me if I knew that she sold a property.So with all this I flew to Texas to see what was going on(in 2014).I contacted the DA's office and they said that because my mom will not talk(she's elderly) as to who did this to her,I couldnt do anything.(asked my mom about this and wouldnt tell me anything)So any way,now this family member she lives in another country (and doesnt want her name on any legal issue)is telling me that the one who was doing this to my mom was this neighbor,and she described her almost perfeclty as this leech neighbor ,who was eager to be my moms poa..and is real savy with the law,supposedly did this to her along with some other person ,according to this family member who my mom confided in with in telling them this. Now,I have the bank records of these transactions,along with records of the home depot transsactions,but of course,unless there was video evidence of this neighbor taking my moms HD credit cards taking it to the cleaners.I have the letter wich my mom sent this family member and other bank records in which she did not fill out the withdrawl forms to take cash out.It was someone or maybe the teller and of course theres a question as to if her signature was forged . I contacted the bank regarding this as possible fraud. Then my mom called the bank to tell them that not to worry that her account was ok.The bank eventually closed my mom's account amid tha fact that they were getting 2 different conflicting statements. And this neighbor still lives near my mom.This family member has shed some needed light on to this issue.No wonder that my mom gets scared when I talk bad about this neighbor sometimes.Given that I've given some details regarding this issue, do I have any legal recourse?
