The identity of the man allegedly responsible for sending one young “Dance Moms” star, reportedly newcomer JoJo Siwa, 12, five suspicious packages, which resulted in an appearance from a bomb squad near Murrysville, Pennsylvania, on Tuesday, has been revealed. According to reports, Phoenix Sundown, 36, has been arrested in connection to the scare.

TMZ reports that Sundown sent the packages, which contained items ranging from blankets, a coffee maker, handwritten letters and nude photos, to a fan mail address. Sundown was arrested in San Diego, California, on Tuesday evening. WTAE-TV reports that he is facing a felony charge of sending “obscene matter to a minor.” He remains behind bars on a $25,000 bond in San Diego County Jail.

So, who is Phoenix Sundown? According to TMZ, he has a criminal history. The site reports that court documents show he was arrested in 2007 for assault and served three years in a state penitentiary. After being diagnosed with an unspecified mental disorder, he was moved to a prison hospital. While being treated, doctors reportedly witnessed Sundown in possession of disturbing photos of women, one which allegedly showed actress Lindsay Lohan with “trails of red dripping down her body and Sundown holding a long knife over her.” A video of Sundown obtained by TMZ shows him smoking a cigarette and zooming in on two tattoos of women on his body, both who appear to be bleeding from the eyes.

On Tuesday, a postal inspector at a Murrysville post office, just over 11 miles from where Lifetime films “Dance Moms,” intercepted five suspicious packages, allegedly from Sundown, intended for the "Dance Moms" star. “They contained items that were inappropriate for minors. Harassing, stalking items,” US Postal Inspector Tammy Maylee told WTAE-TV. An Allegheny County bomb squad shortly after arrived on scene to destroy the packages, using a water cannon to do so. Maylee says the items inside the packages “were hazardous in nature” but did not contain bombs.

TMZ reports the packages were not Sundown’s first attempt at connecting with the young “Dance Moms” star. According to the site’s findings, Sundown would post photos of kidnap survivor Elizabeth Smart on Twitter and tag the young reality star, saying, “#futuregoals.” 

Sundown is reportedly married to a 93 year old woman.

“Dance Moms” premieres on Lifetime in 2011. The reality series follows several moms and their daughters as they compete in dance competitions under the instruction of coach Abby Lee Miller. The show wrapped its fifth season in August and is expected to begin filming Season 6 in the coming months.
