Pfc. Melissa Kendall of Silver Spring, a member of the Takoma Park police department since 1980, has been named Takoma Park Police Officer of the Year for 1985 for saving the life of a 3-year-old and for the many criminal arrests she made last year. Last fall, according to police, a Takoma Park boy fell 42 feet from an apartment balcony. The boy was not breathing when Kendall arrived at the scene, and she revived him with mouth-to-mouth resuscitation. Police said doctors at Children's Hospital, where the boy was taken, credit Kendall with saving his life and preventing brain damage.

Two other Takoma Park police officers also received Awards for Meritorious Service. Pfc. Barbara Strickland, a member of the community services unit, was recognized for her presentations to community and school groups on crime prevention and safety for "latchkey" children.

On her own initiative, she upgraded the department's crossing guard program and secured private funding for department equipment, police said. Strickland, who has been with the force since 1974, lives in College Park. Pvt. Scott McAuley was commended for the nine "crime-in-progress" arrests he made out of a total 35 criminal arrests. McAuley, who joined the force in 1984, lives in Takoma Park. Shipp Named to D.C. Youth Ensemble
