Prosecutors will seek the death penalty for the man accused of shooting to death two people on the Las Vegas Strip. Manuel Ruiz, 41, was indicted last month on two counts of murder with use of a deadly weapon.

New York City police detectives searched the Las Vegas studio apartment of the suspected gunman in Monday's mass shooting at a Midtown Manhattan office tower and found what law enforcement sources described to ABC News as a suicide note he left for his parents.
