An attorney for Michael Jackson's mother confirms that child services workers are investigating the presence of a stun gun at the Jackson family home, but he says the late singer's children were never exposed to the weapon. Attorney Adam Streisand confirmed the investigation Tuesday, but said the mail-order stun gun delivered to the home was confiscated before any harm was done. Streisand represents Katherine Jackson, who has custody of her son's three young children, Prince Michael, Paris and Prince Michael II, also known as Blanket. Streisand said the weapon was ordered by the 13-year-old son of Jermaine Jackson, Jafar, and sent to the Jackson family home in the Encino neighborhood of Los Angeles. Jermaine Jackson's children also live in the home. “Jafar opened the package in his bathroom and tested it on a piece of paper,” Streisand said in a statement. Security and Katherine Jackson heard the sound and confiscated the weapon immediately, he said. Streisand said Michael Jackson's oldest son, Prince, saw the stun gun after it was taken by security. Katherine Jackson has been caring for the children since their father's death June 25 at age 50. The children range in age from 8 to 13.
