His older half-sister was Daisy McConnell (1901–1904) and his younger sister was Lucille Fay LeSueur (1906–1977), who later became an actress with the stage name Joan Crawford.

The other car caught fire and the three people inside (Earl Gose, who was driving; his wife, Golda; and his sister, Grace) were pulled from the blaze.

[11] LeSueur suffered severe cuts and bruises on his hands, face, arms and legs.

Golda, who was taken into court on a hospital stretcher, which was placed before the jury box, testified that LeSueur was driving on the wrong side of Cahuenga Boulevard when his car collided with theirs.

LeSueur not only denied responsibility for the accident, but in his cross-complaint for $10,000 charged that the crash came about through Gose's negligent driving.

LeSueur made one final movie appearance, playing a reporter in Jeanne Eagels (1957).

He made one TV appearance in an episode of the series State Trooper, titled No Fancy Cowboys, which aired on 13 March 1957.

His sister, Joan Crawford reportedly sent him telegrams from New York to the hospital before he died, but did not attend his funeral.
