In 2009, Marta del Castillo, 17, went missing in Seville, Spain, and still to this day, her body has never been found. Now, the teenager's disappearance is being explored in Netflix's new true crime series Where is Marta? - and viewers have left viewers shaken by the case.
Marta had told a friend over social media that she was meeting up with her ex-boyfriend, the 19-year-old Miguel Carcaño Delgado, who confirmed they met that evening before she disappeared. He later confessed to murdering her but changed his version of events several times.
The key change to his confessions was the means of disposing of the body, initially saying he dumped her body in a river and then later claiming he disposed of it in a dumpster. Delgado was convicted of murder, but Marta's body has never been found.
One viewer warned others on Twitter: "Where is Marta? on Netflix will have you wanting to scream at the television, so upsetting."
Another agreed and gave their full review: "Mannnnn if you haven't check out "Where Is Marta" on Netflix ....real crime documentary and this sh*t will have you just screaming at the TV cuz ain't no f**kin way Rate: 9/10".
It proved to be a tough watch for many, with one tweeter saying: "My mom and I shedding tears at the end of where is Marta".
"Just finished watching 'Where is Marta' on Netflix and it's given me the chills", someone else tweeted.
Others also accused the police of failing to do a sufficient job with one person sharing: "Where is Marta, riveting and upsetting, the inefficiency of #Seville Police is appalling".
This viewer also noted the ongoing struggle of Marta's family: "Where is Marta is another heart-wrenching documentary on #Netflix What this family went through (and still going through) is unimaginable".
Another person shared the sentiment: "On to Ep2 of 'Where is Marta?' on Netflix.. it's just so sad & tragic. Her parents are so strong".
Somebody else also hoped for some closure for the family: "The Netflix series about Marta del Castillo is infuriating and so upsetting for her family. Surely Justice will be server and her body recovered soon."
Where is Marta? is available to watch on Netflix.
