“Bampumim Teixeira, 30, was charged with two counts of murder as it emerged he used to work as a security guard at the luxury complex where his victims lived.
“He got access to their $1.9million (£1.5million) apartment in Boston, Massachusetts, and allegedly slit their throats before trying to steal a bag of jewelry, police say.
“Dr Richard Field, 49, and Dr Lina Bolanos, 38, were murdered after Teixeira, who is originally from West Africa, burst into their penthouse on Friday evening, police say.
“Teixeira, who was shot in the hand, abdomen and leg in a shootout with police, entered two not guilty pleas from his hospital bed at Tufts Medical Center.
“Judge Michael Bolden ordered Teixeira to be held without bail and court-appointed defense attorney Steve Sack did not argue for bail. His next court date is June 8.
“Teixeira is originally from Guinea Bissau and immigrated to America with his aunt at an early age, according to the Boston Globe.
“Dr Field was born in Hammersmith, West London, and graduated from the University of Sheffield’s Medical School in 1999. He lived in Broomhill during his time in the city.”
