Han­nah Mathu­ra was shot in the head and then buried in a shal­low grave at the fam­i­ly's home in Val­sayn.

The ex­act cause of death was con­firmed by se­nior po­lice of­fi­cials late yes­ter­day who told Guardian Me­dia the find­ings in­di­cat­ed she died as a re­sult of "gun­shot in­juries to the head."

He said all oth­er in­juries were un­able to be dis­cerned.

And as the in­ves­ti­ga­tion deep­ened yes­ter­day, of­fi­cers are now look­ing to de­ter­mine whose gun was used, where it is now, and just who would have shot Mathu­ra as the two sus­pects that re­mained in cus­tody yes­ter­day, were not hold­ers of a Firearm Users Li­cens­es (FUL).

A 62-year-old woman and a 66-year-old man who are close rel­a­tives of the mur­dered teenag­er, were ar­rest­ed on Thurs­day af­ter her skele­tal re­mains were found in a shal­low grave at the fam­i­ly home in Val­sayn ear­li­er this week.

In­ves­ti­ga­tors said they could be fac­ing mul­ti­ple charges as the in­ves­ti­ga­tion con­tin­ues.

Among them is mur­der, as well as the un­law­ful dis­pos­al of a body.
