India, July 27 -- A couple and their two minor children were found dead after allegedly jumping into a water tank in Rajasthan's Jaisalmer district on Sunday night, police said.

Station House Officer (SHO) Devkishan said, "We received information about the deaths of four members of a family and immediately reached the hospital and the incident site. Prima facie, it appears to be a case of murder-suicide, but all possible angles, including any foul play or conspiracy, are being thoroughly investigated."

Police suspect the parents first threw the children into the tank before taking the extreme step themselves, though they said all angles, including foul play, are being investigated.

The incident took place around 9pm in Loharki village....
