CCTV footage has emerged showing the final journey of Emad Al-Swealmeen on his way to sow terror at Liverpool Women's Hospital.
The Iraq-born 32-year-old was the only fatality after a home-made bomb exploded in the back of a Delta taxi outside the specialist maternity hospital just before 11am on Sunday.
The driver, David Perry, leapt from the vehicle seconds after the blast before it was incinerated by flames.

Counter terrorism police are ploughing on with a fast-moving investigation and this morning announced they believed Al-Swealmeen had been planning the attack since April, when he moved into an address on Rutland Avenue, near Sefton Park.
So far detectives are not seeking anyone else in connection with the bombing, although they remain open-minded.
The ECHO has since learned that Mr Perry's taxi travelled along Lodge Lane on its way to the Crown Street site, and was captured by cameras at The Green Mountain Food Store, by the junction with Tagus Street.
Manager Naz Al-Asadi, 27, told the ECHO: "The police came in around 12pm yesterday, they said to me can we check the CCTV.
"I said yes, we should work together as this is something not good at all, this is very, very bad.
"They knew the time and they took a copy.
"It is very horrible, very very bad. I just want to know what was going on with this guy, it is not normal."
Police also visited other shops in the busy street, and staff and residents spoke of their dismay at hearing about the attack.
One young man, working in a phone repair store, told the ECHO: "I have no words to say about this guy who done it.
"We feel it paints a bad picture for us as Muslims, although he converted to Christianity. It is nothing to do with the Muslim people.
"I have heard about people that I know, women with the hijab, saying things to them about the situation."
The motive behind the attack has not been confirmed by Counter Terror police so far.
Al-Swealmeen had accessed mental health services since his arrival in the UK in 2014, but Mersey Care NHS Foundation Trust told the ECHO he was not a service user at the time of his death.
According to friends he was sectioned in 2015 after being prosecuted for possessing a knife in the city.
The BBC reported he had an asylum claim turned down, and had lodged an appeal with the Upper Tribunal of the Immigration and Asylum Chamber.
That was dismissed in 2017, and his asylum status at the time of his death is unclear.
It has also emerged Al-Swealmeen had embarked on a cake decorating course at City of Liverpool College in 2018.
Assistant Chief Constable Russ Jackson, Head of Counter Terrorism Policing North West, said: "The investigation into the terrorist incident at Liverpool Women's Hospital on Sunday 14 November continues.
"The taxi in which the device exploded has now been removed and today line searches by specialist officers will take place at the Hospital which could go into tomorrow.
"The post mortem on the deceased has taken place and the cause of death has been described as injuries sustained from the fire and explosion.
"A complex picture is emerging over the purchases of the component parts of the device, we know that Al Swealmeen rented the property from April this year and we believe relevant purchases have been made at least since that time.
"We have now traced a next of kin for Al Swealmeen who has informed us that he was born in Iraq.
"Our enquiries have found that Al Swealmeen has had episodes of mental illness, this will form part of the investigation and will take some time to fully understand.
"There is much comment in the media about Al Swealmeen and it is clear that he was known to many people.
"We continue to appeal for people who knew him, especially those who associated with him this year as we try and piece together the events leading up to this incident and the reasons for it.
"At this time we are not finding any link to others in the Merseyside area of concern but this remains a fast moving investigation and as more becomes known we cannot rule out action against others."
