Who called me from this phone number (323) 709-4048

My sister killed herself after getting this Social Security scammer call. My sister, Jillaine, was a ward of the state because she was bipolar, paranoid schizophrenic, epileptic, has had 2 brain surgeries to remove some lesions and a VNS device brain implant to help control her seizures. She also had a Social Services nurse visiting her daily to give her her medicine. She had a landline phone, not a cell phone because they confused and upset her. On Thursday, June 27, 2019 at either an Unknown number @6:16pm or spoofing # Austin Tx (512)219-1617 @6:13pm called my sister. These are the only numbers showing on her call ID that are unknown to us. She then called her friend, who told her it was probably a scammer. He told us that it had said it was the IRS or a Government agency saying they were going to arrest her and take away her Social Security. Now, you have to understand that she lives completely off Social Security, Medicare and Food Stamps. She only had $2 in her wallet. She then tried calling the Social Security, but the line said over an hour wait, but she called him back in less than 45 minutes and told him it was, "Just fine.". She gave up waiting. She gave up hope. She was found on the floor the next morning after having ingested cleaning chemicals. Today, I was going through my voicemails, and I too got a call from this automated voice telling me that my Social security number will be blocked by 'government agencies'. It then goes on to give the number to call of (323)709-4048. Now this may or may not be the same number given in the recording I made of the voicemail, time was going to erase, but it was the same automated intention of thievery from the naive and or infirmed. I would curse every one of them if I could, if it would bring back my sister and stop them from doing it to someone else. Catch these horrible, heartless, subhuman animals!
