Question: What WWE event happened during the period of June 22-25, 2007, which is the same weekend as another event involving a WWE wrestler? 

<P0-S0> Over a three-day period between June 22 and June 25, 2007, Chris Benoit, a 40-year-old veteran professional wrestler employed by World Wrestling Entertainment (WWE), killed his wife Nancy Benoit and strangled their 7-year-old son Daniel before hanging himself. <P0-S1>  Autopsy results showed that Benoit's wife was murdered first as she was bound at the feet and wrists and died of asphyxiation on Friday. <P0-S2>  Nancy was found wrapped in a towel and with blood under her head, although Fayette County District Attorney Scott Ballard reported no other signs of a struggle. <SEP> <P1-S0> WWE Extreme Rules (simply known as Extreme Rules) is a professional wrestling event produced annually by WWE, a Connecticut-based promotion, and broadcast live and available only through pay-per-view (PPV) and the WWE Network. <P1-S1>  The name of the event stems from most matches being contested under hardcore wrestling regulations; the defunct Extreme Championship Wrestling (ECW) promotion originally used the term to describe the regulations for all of its matches. <P1-S2>  The event name was established in 2009; however, its theme began with its predecessor, One Night Stand, which was promoted in 2005 and 2006 as an ECW reunion show. <P1-S3>  In 2007, WWE promoted the show as one of its own regular PPV events but kept the ECW concept of Extreme Rules matches. <P1-S4>  In 2009, WWE renamed the One Night Stand event to WWE Extreme Rules. <P1-S5>  The 2009 Extreme Rules event was noted by WWE to be a direct continuation of the One Night Stand chronology. <P1-S6>  However, the 2010 event was later promoted as only the second event under a new chronology, one that is no longer a direct continuation of the One Night Stand events. <P1-S7>  Starting in 2010, Extreme Rules was moved from June to late April/early May to replace Backlash as the post-WrestleMania pay-per-view event. <P1-S8>  For 2013, the event was scheduled to take place in mid-May and replace Over the Limit, which was moved to October before being discontinued later that year and replaced by Battleground. <P1-S9>  The event will return to the early June slot of WWE's pay-per-view calendar and will be a Raw-exclusive pay-per-view event. <SEP> <P2-S0> Vengeance: Night of Champions was the seventh annual professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE) within its Vengeance/Night of Champions chronology. <P2-S1>  It featured talent from the Raw, SmackDown! <P2-S2> , and ECW brands. <P2-S3>  The event was sponsored by Raw Attitude Energy Drink and took place on June 24, 2007, at the Toyota Center in Houston, Texas. <P2-S4>  Every match on the card was contested for a championship; two were won and seven were retained. <P2-S5>  This event was notable for being on the weekend of the Chris Benoit double-murder and suicide case. <P2-S6>  Benoit, who was originally booked to face CM Punk for the vacant ECW World Championship, legitimately no-showed. <SEP> <P3-S0> Aperiodic frequency is the rate of incidence or occurrence of non-cyclic phenomena, including random processes such as radioactive decay. <P3-S1>  It is expressed in units of measurement of reciprocal seconds or, in the case of radioactivity, becquerels. <P3-S2>  It is defined as a ratio, "f" = "N"/"T", involving the number of times an event happened ("N") during a given time duration ("T"); it is a physical quantity of type temporal rate.
