PHILADELPHIA -- Allen Iverson prepared to surrender to police on charges he burst into his cousin's apartment with a handgun and threatened two men.

The 2000-01 NBA MVP has been confined to his $2.4 million house since prosecutors announced last week they would charge him and his uncle with assault, terroristic threats and related offenses.

Iverson also faces gun charges. The 27-year-old Philadelphia 76ers guard and his uncle were expected to turn themselves in Tuesday.

Iverson's mother defended her son in front of the mansion where he has been holed up for five days.

"I know my son,'' Ann Iverson said Monday night. "I know my child isn't capable of this crazy stuff.''

Iverson allegedly threw his wife, Tawanna, out of their suburban mansion during a fight, then barged into the cousin's Philadelphia apartment with a gun while searching for her the next night. Iverson and his uncle allegedly threatened two people inside the apartment -- 21-year-old Charles Jones and 17-year-old Hakim Carey.

Police have searched Iverson's house and vehicles, but are not believed to have found a weapon.

In a court document filed Monday, police said one of the searches turned up two cell phones, a phone bill, other phone company documents and auto body repair documents. There was no mention of a gun. The police document did not say whether the search was of Iverson's house or cars.

Curiosity-seekers have been coming to Iverson's house for days, hoping to catch a glimpse of him or his wife. Reporters and photographers have been camping outside.

Iverson has not been seen outside the house since about 5 a.m. Sunday, at the end of a party with friends and relatives. The last glimpse of his wife came Wednesday. Neither spoke with reporters.

The last statement from Iverson's Virginia lawyers was July 8, when they issued a news release confirming they had met with police. One lawyer, hired last week, has been vacationing in Europe. Another repeatedly declined to comment.

When Iverson turns himself in, he'll be fingerprinted, photographed and given a booking number. Then he'll wait for his preliminary arraignment.

Police say Iverson won't be moved up in line, although he will be allowed to meet with his attorney like any prisoner awaiting arraignment.

The charges will be read to him, he'll enter a plea and then bail likely will be set.

"It's a very time-consuming and tedious process to go through for anyone who's in custody,'' police inspector William Colarulo said.
