"Please stay with me on the line, I'm really scared," Alexandra Macesanu told a police officer while crying during her third and last call, according to a transcript released on Facebook by her uncle Alexandru Cumpanasu.
The suspect, 65-year-old mechanic Gheorghe Dinca from Caracal in the south of the country, has told police he killed the 15-year-old and another girl.
The teenager, who is now presumed dead, disappeared on 24 July - and Luiza Melencu, 18, was last seen in April.

Romania's national police chief and two county officials were fired last week following a public outcry over the handling of the case.
Mr Florescu, a police officer from the nearby town of Slatina, told local media that he talked to Alexandra twice and gave her details to Caracal police.
Mr Florescu said: "I repeatedly told her to stay calm and that a police car was coming". »
