Man on Trial for Chilling Double Murder and Dismemberment in London
Brutal Killings Shake London and Bristol
A man stands accused of a grisly double murder that has stunned the capital. Yostin Andres Mosquera, 35, is on trial at the Old Bailey for allegedly killing and dismembering Albert Alfonso, 62, and Paul Longworth, 71. The horrific attack happened at their flat in Shepherd’s Bush on July 8, 2024.
Mosquera denies the murders but admits to manslaughter of Mr Alfonso, claiming he lost control.
“Decapitated and Chopped Up” – The Prosecution’s Account
Prosecutor Deanna Heer KC told the court Mosquera murdered Mr Longworth with a hammer and stabbed Mr Alfonso multiple times. Then came the shocking mutilation – Mosquera allegedly dismembered and decapitated the victims.
He stored their remains in a chest freezer before packing them into suitcases. The jury heard disturbing testimony of Mosquera calmly filming the aftermath, even singing and dancing beside one victim’s dying body. The prosecution called the acts “strategic and premeditated,” dismissing claims of a loss of control.
Attempted Theft and Fake Alibi Exposed
After the murders, Mosquera allegedly tried to cash in—stealing banking details and transferring money to himself. He made several withdrawals and faked messages pretending to be Mr Alfonso.
Investigators uncovered chilling online searches on Mosquera’s computer, including “serial killers of London” and browsing Facebook Marketplace for chest freezers – all before the murders.
Shocking Discovery at Clifton Suspension Bridge
Two days after the killings, a cyclist spotted Mosquera near Clifton Suspension Bridge with two suitcases. When bridge staff noticed liquid leaking from one, police were called. Inside, officers found human remains linked to the victims.
Mosquera fled but was arrested at Bristol Temple Meads Station on July 13. The case has left London and Bristol communities reeling, with neighbours describing the victims as a “friendly couple who seemed genuinely fond of each other.”
Trial Continues at the Old Bailey
Mosquera faces a full trial for double murder, with prosecutors arguing the killings were a cold, calculated move to steal money. The verdict will be closely watched by shocked residents still coming to terms with the brutality of the case.
