A man called my mother pretending to be her nephew.  He fished for a name and said he was coming to visit tomorrow.  When he called again, we asked him a couple of questions that proved he was an impostor.  He told him so and he hung up.

Somebody called my ant in Florida pretending to be me, and that I was Vacation trip to Cancun, Mexico.This person told my ant that he had the intention to stop by in the way back to visit them. Apparently and somehow this person had some information about my family names, etc. It is very disturbing to find out that there is people out there trying impersonate me, especially pretending to be a member of my family. These people are dangerous and can commit other crimes, like getting into your banking account, credit card, or social security in order to commit fraud.

We just got robbed by this guy. He had information about the family members and called our home. He said he was coming to visit and that he had a car accident. He requested a money transfer to Mexico. Unfortunately my family member beloved him and lost more than a $1000 in cash. We reported it to the police but no further action has being taken. Let's spread the word about his criminal.

Yes.
That scam  has been noted previously.  Too bad your family was unaware of it.

Here is the description:

The scammer may speak Spanish, and may target Hispanics in the USA. He attempts to convince the called person that he is a relative, and will be visiting for a few days. If the called party expresses any interest, the scammer promises to call back. When the scammer calls back, he tells the called party that something happened - he ran out of gas, or was stopped by the police, or is being held at the airport, or needs money for some other reason -- he wants you to wire the money to him immediately.

If you send money, it will disappear, along with the "relative".

A man (with Cuban accent) called my home, my wife answered and he pretended to be her nephew, he gave her my family name, and stated that is from the part of the family that lives out of town. My wife did not give more information (we are the only ones in the family living out of our towns) and when she started asking him questions he immediately hung up.
