NEW YORK (TheStreet) -- Vale (VALE) - Get Report stock is declining by 5.95% to $2.92 in afternoon trading on Wednesday, as Brazilian police accuse six Samarco executives and one contractor of murder.

The Samarco Brazilian mining company is a joint venture between Vale and BHP Billiton (BHP). 

A Samarco dam ruptured in November, and the police allege that the problem was caused by overfilling in conjunction with a lack of monitoring and faulty equipment, Reuters reports.

Nineteen people were killed after the dam burst, and the event is considered Brazil's worst environmental disaster. 

Separately, TheStreet Ratings team rates the stock as a "sell" with a ratings score of D.

Vale's weaknesses include its disappointing return on equity, weak operating cash flow, generally disappointing historical performance in the stock itself and feeble growth in its earnings per share.
