A Silver Spring man who reported his 6-year-old daughter missing 10 days ago was committed for psychiatric evaluation yesterday by his estranged wife after police executed a search warrant at his home, according to police and the man's attorney. The search for the child was continuing.

Carl Dorr, 33, was taken to the Washington Adventist Hospital, according to his lawyer, David Goldberg.

Dorr told police he last saw his daughter, Michele, playing in a wading pool in the back yard of his house in the 9100 block of Sudbury Lane on May 31 while he was inside watching the Indianapolis 500 auto race on televison. Michele was living with her mother in Gaithersburg and was visiting her father.

Montgomery County police Detective Michael Garvey said a warrant to search Dorr's home was obtained from the county Circuit Court yesterday and that the search lasted about an hour. "Nothing was recovered or obtained" in the search, he said.

Garvey declined to say what prompted the search. He said police have "no new leads" to the girl's whereabouts.

Last Thursday, Dorr was summoned to testify before a Circuit Court grand jury investigating the girl's disappearance, but he invoked the Fifth Amendment and refused to answer questions. He said then that Goldberg had told him police considered him a suspect and that his responses could incriminate him. Dorr has contended that investigators have attempted to intimidate and harass him, but police have denied doing so.

The next day, following a brief meeting in chambers with Circuit Judge William Miller, Dorr said he intended to "cooperate fully" with the grand jury and police.

Goldberg said that since then Dorr has been questioned twice by police and submitted to a polygraph test.

Dorothy Dorr said her husband arrived at her home in Gaithersburg Sunday night and stayed there until 4 a.m. yesterday.

Goldberg said Dorothy Dorr signed a petition to have her husband committed to the hospital for "short-term involuntary commission for an involuntary psychiatric evaluation."

"He just lost it, he had a mental breakdown," Goldberg told a reporter last night. "The accusations being made, and the press always being in his face just got to him," Goldberg said.

The National Missing Child Society has offered a $20,000 reward for information leading to the whereabouts of Michele Dorr and has asked anyone with information to call (301) 843-6608.
