A sus­pect who has been ar­rest­ed in re­la­tion to the mur­der of 20-year-old Sa­van­na Dy­er has been sent to the St Ann’s Psy­chi­atric Hos­pi­tal for eval­u­a­tion, po­lice said.

Dy­er’s body was found in an aban­doned par­cel of land on Xeres Road, Carlsen Field, on Sat­ur­day morn­ing.

In­ves­ti­ga­tors said blood was vis­i­ble on her face and marks of vi­o­lence were ev­i­dent on the body.

An au­top­sy yes­ter­day con­firmed that Dy­er’s cause of death was due to a sin­gle gun­shot wound to the head.

Po­lice con­firmed that two men were ar­rest­ed in re­la­tion to the mur­der. One of the men sur­ren­dered to the po­lice, while the oth­er was ar­rest­ed near his home.

Sources said one of the men was sent to St Ann’s on Tues­day to as­sess his men­tal com­pe­tence, while the oth­er re­mained in cus­tody at a po­lice sta­tion in the Cen­tral Di­vi­sion.

Guardian Me­dia un­der­stands that the Di­rec­tor of Pub­lic Pros­e­cu­tions has not yet been ap­proached for ad­vice on what charges if any should be laid against the sus­pects.
