RIO DE JANEIRO (AP) — Brazil's investigative police say they're seeking homicide charges against 19 people in the deaths of a man and a woman caused by the collapse of unfinished overpass in the World Cup host city of Belo Horizonte.

Police investigator Hugo e Silva said he sent the results of his probe to prosecutors on Wednesday.

He says those named in his probe demonstrated a "disregard for basic norms of safety" by failing to correct problems in the structure, even after being repeatedly warned by specialists. Those implicated include government officials and architects, as well as engineers for two construction companies,

Another 23 people were injured in the July 3 collapse. A bus, two construction trucks and a car were crushed beneath tons of concrete and steel on a major thoroughfare.
