The H 2 molecule is a good example of the first type of covalent bond, the nonpolar bond. Because both atoms in the H 2 molecule have an equal attraction (or affinity) for electrons, the bonding electrons are equally shared by the two atoms, and a nonpolar covalent bond is formed. good example of a polar covalent bond is the hydrogen-oxygen bond in the water molecule. Water molecules contain two hydrogen atoms (pictured in red) bonded to one oxygen atom (blue). Oxygen, with six valence electrons, needs two additional electrons to complete its valence shell. Each hydrogen contains one electron.
No one was ever convicted of the crimes, but one man confessed. Albert DeSalvo, already in custody for robbery and sexual assault, claimed to be the Strangler. Serving his sentence in Bridgewater State Hospital for his other crimes, DeSalvo escaped with two other inmates and triggered a massive manhunt. He was captured the next day, Feb. 25, 1967.
No one on this night was held for any of the murders to date. The Boston Strangler first struck on June 14, 1962, and the panic that gripped the city lasted until after the last victim died on Jan. 4, 1964.
