The suspect, Ayumi Kuboki, 31, admitted the fresh murder allegations against her, the Kanagawa prefectural police department said.
According to the third arrest warrant, Kuboki allegedly killed Asae Okitsu, 78, by injecting an antiseptic into an intravenous drip bag for her kept at the nurse station on the fourth floor of Oguchi Hospital, now Yokohama Hajime Hospital, around between 7:45 a.m. and 5:30 p.m. on Sept. 15, 2016.
Okitsu's condition worsened suddenly after the intravenous drip was administered to the patient by a different nurse on the morning of Sept. 16, and she died around 1:40 p.m. the same day, according to the police.
Okitsu was initially judged to have died of illness. But the same surfactant substance as that used in the antiseptic was detected in her blood sampled before her death.
