A man suspected to have killed an American man and his wife at their residence near Tokyo in December was served a fresh arrest warrant Monday over the death of their daughter, also found at the scene, police said.

Jun Saito, 40, was a neighbor of William Bishop, a 69-year-old U.S. national, and his wife Izumi Morita, 68. The couple and their daughter Sophianna Megumi Morita, a 32-year-old who was living in Tokyo's Shibuya Ward, were found dead with blunt trauma injuries on Dec. 25 at Bishop's residence in Saitama Prefecture.

According to the police, a security camera at the residence had recorded a scene of the attack, including a man who appeared to be Saito.

The police has also confiscated multiple blunt objects from the home of Saito, while DNA from blood found on clothing and gloves seized from his home matched that of all three victims.

Saito was sent to prosecutors on Dec. 27 for allegedly killing Bishop and was served a fresh arrest warrant on Jan. 16 for the alleged murder of his wife. He has denied the allegations in both cases, police said.
